Part one here.

How do we Provoke, Scare and Pierce the (Driver’s) primitive Reptile Brain? How do we stay alive?

We look to nature and the development of the brain in the animal kingdom. Evolutionists (which I am not) have no problem with this concept. Yet, observation leads to irrefutable conclusions. Most all organic organisms in nature, no matter how “primitive/paleo” or presumably “advanced”, share common traits… like all have and share DNA similarities for example…

Even the “simple”, primitive, prehistoric paramecium3 (see link below) are highly sensitive and flee from bright light. And likewise, so too our own human visual cortex, directly wired in the brain; via the Amygdala, Basal Ganglia, and Hypothalamus via the Limbic system (or paleomammalian brain)… These gray, and convoluted features are understood (some say known) to be the deepest and most primitive unconscious areas of our human brain (along with the medulla & cerebellum).

While this isn’t a physiology paper, the point to be made is that the “Fight or Flight” mechanism mentioned much earlier, needs to be completely, totally, and unconditionally activated and profoundly stimulated at a very low and unconscious level; in the vehicle driver’s brain.

It turns out that just like paramecium, and many reptiles, ULTRA BRIGHT FLASHING RED LIGHTS are immediately sensed by humans as “threats”.  As a life form is “threatened”, certain physiochemical responses are unconsciously activated…. the “Fight or Flight involuntary mechanism. Immediately the higher functions of the cerebrum are bypassed, and the visual cortex “reaches down” to the primitive reptile brain and causes/induces FEAR, and the autonomic, unconscious brain triggers the release of some very powerful stimulant hormones. Now; close your eyes; and imagine that you are outside in the dark tall grasses, and you feel and hear the low strong growling of a nearby lion; hear tires squealing, a loud close Bang!, etc… you get an idea of what the driver’s EYES are seeing…

Why flashing lights?…and Not solid? Flashing create and induces the appearance of Motion. Movement is the key to being detected by the Reptile brain. We want and need to be detected and identified, from the greatest possible distance.

Alternatively; waiting for any driver to see and consciously recognize you riding away, in dark clothing from a distance, then comprehend, and avoid you, turns out to be a quick death march for cyclists.

Flashing Bright Light(s)… Our only reliable solution, “defence against the…?”

“Statistics don’t lie”… my college statistics professor often told us, (countless others have made the same statement/observation). What we learned in school is that (in a fair and well designed study) the numbers are what they are, for a reason. It doesn’t matter what that reason is… The (possible) reasons/explanation that the stock market climbs or drops is incidental and unimportant. Using math to measuring the speed and momentum (emotion) of the rise and fall is what is critical. Why do I mention this seemingly unrelated topic?

(Another) Spoiler Alert: The statistics for riding with Flashing Ultra Bright lights is literally breathtaking, from one perspective, and alarming from another. In addition to the 700 KILLED riding a bike in the US every year, there are over 500,000 cycling injuries. Let’s say the 2/3rs mentioned at the beginning of this article, or roughly 5,000 cyclists in the last ten years alone, were hit from behind, and died… The cyclist had no warning or defense to prevent his/her death.   In the other 1/3 of fatal accidents, most often the cyclist either had some visual warning and possible responsibility (steered into traffic, went across a rail road crossing, etc.) in the outcome of the accident, or some warning. Not the case of “hit from behind” fatalities. That again, is where I draw the line.

In now two plus years of research, I have Yet to find a single, confirmed, instance where the killed cyclist was riding with Ultra Bright Lights turned ON at the time of the accident. 500,000 injuries, 7,000+ deaths (without lights) to (so far) ZERO (With Lights)… (EVEN if one or two have been missed, the numbers are far more than compelling.)

Note; as of the week of 6/12/15 there were (2) reported fatalities (bikinginla.com) where it appears the riders did have lights on the rear of their bikes…. See/Read article “Testing to Destruction” for more information… So now the numbers are over: 500,000 : 000002.

The numbers are REAL.   In this singular case, my statistics professor was (dead) wrong. It DOES MATTER why the numbers are the way they are. Important Note; Several times I would/have heard it said; He/she (the victim) was “lit up like a Christmas tree”… but later found out from eye witnesses, their cycling buddies, car cam videos, accident pictures, or the police interviewed, that they had no lights at all. Don’t believe everything (anything) you hear until you have verified it for yourself.

My story: Like many, perhaps most victims, I went on a Crusade; to find “the answer”, “the solution”, to prevent what had happened to me, from happening to others. After being released from the hospital and in time regaining some memory and “normal” lifestyle, I set out on this quest.   As stated, I have found this characteristic is deeply imbedded in the deepest being and recesses of most victims. Every time I hear of a cyclist fatality, I relive my own accident; I literally feel the glass and metal pushing/smashing through my own face, and body…

Utilizing a previous positive relationship with of a couple PD’s and the L.A. County Sheriff’s department, I started my quest. I wanted to see and learn everything I could about fatality accidents. This process is ongoing and will likely last my lifetime.

What I learned (am learning) from adding up and compiling the numbers, is that 2/3 rd’s of fatality accidents fall in the “hit from behind” category. The problem is that the standard Highway Patrol accident report form, used by all law enforcement departments, is inadequate and lacking in a number of areas. I started with the three fatalities in Newport Beach almost following my accident.

I noticed that none of these first few fatality victims’ bikes had any lights at all.   I started to develop a theory. Could it be valid and true? The problem is that the CHP standard traffic collision report form does not have a checkbox for “rear Lights? ON?”

Obtaining reliable information was difficult. What did I do? Reports, Pictures and Questions. Without going into details that would compromise others, I talked directly to officers, or obtained photos of the actual accident scenes. Not just any pics, only those specifically of the bikes, without any people. (I specifically didn’t ask nor want pics with any people in them, and no one offered.)

I continue to search accident reports and witnesses; to see IF the bikes had rear lights, what type, and did anyone know IF the lights were CHARGED and ON at the time of the accident. What time of day was the fatality crash? Where? What were the conditions? Those were/are my questions.

A clear and obvious pattern began to emerge. No fatality accident bikes, had lights at all. Not one. I was also looking for lights that were so cheap/poor as to be worthless, even if they were turned on, but haven’t found any yet.

Time after time, death after death, I found no lights… I knew it was “ game on”…

Then I interviewed drivers, and read the PD reports. As mentioned earlier, what I heard was scarily familiar, ominous, and consistent with every one.“I never saw them”….

Every driver report, and every police interviewed driver, unrelated by age, sex, residence area, or ethnic background… all said the same thing… almost word for word… This clearly wasn’t a coincidence. This was/is a Real phenomena. They had killed a cyclist before they ever knew what had happened. Most of these people would otherwise be considered good citizens. Most (one exception) had no criminal record. Yet Everyone of them had killed another human being. That’s scary.

So why weren’t accidents found with riders using Flashing Ultra Bright lights? That became the burning question. What was mentally, visually and physically happening? I started testing lights, with the help of colleagues and very expensive borrowed equipment from a company that I do business with. Some of the testing was very technical requiring calibrated equipment, and some was done using human subjects in blind (brighter/dimmer) visual studies…

What was true in all light tests, was/is that Brighter is better. (we’re not going to be discussing beam angles, target size, protocols for standardized brightness measurements, etc., in this article, that’s another paper).  For the sake of this article, I’m defining Brightens here in strictly relative visual observations; as the ability to see a Flashing light, in broad daylight, from some distance X. The farther away a Flashing light is able to be clearly seen, the “Brighter” it is defined to be… for this article…(more in light reviews).

“Brighter” means that the car drivers can see you from a farther distance. The greater the distance, the more time the driver has to see, recognize, and react to avoid you. Some of my lights, perfectly acceptable at night, couldn’t even be seen in the daylight from 10 yards, not good.

What was the minimum “brightness” between life and death”? How much recognition and reaction time was necessary to make the difference, to prevent a conflict and dead body?

“I never saw them”… started to haunt me. What IF those same drivers had been alerted to the cyclist from a Geat distance, (30-60 driving seconds away)… instead of finding out, only milliseconds before or just after they heard the crashing, crushing horrible crushing sounds?

Rule # 4   Time and Space: Planning time for Avoidance VS. (0) REACTION TIME…

You Hockey players are familiar with the term “Time and Space”… The imperative life/death question boiled down to this: How to effectively and reliably CREATE “TIME AND SPACE” between US (CYCLISTS) AND DRIVERS?

I bought more lights. Lots of lights. From countless observations, I set “standard” protocols to visually test them during daylight, and at night.

Minimum Acceptable Standard (MAS)… 1/10th of a mile minimum visibility looking almost straight at; only 10 degrees off the 10AM morning summer sun. In other words, the worst possible conditions.

In addition to visual testing with multiple subjects, from professional resources, I borrowed high end equipment (worth $50,000+), utilized the optics testing and light meters at the college I teach at. Then applied standard LED FAA aircraft LED testing protocols … Many lights visually tested to ¼ (.25) mile in daylight. That’s 15 seconds warning, even at highway speeds… a very good start…. Some were clearly seen flashing at ½ (.5) mile away… That gives a driver 30-40 seconds to see, identify, and react…. an ETERNITY relative to the previously reported 0 – milliseconds by fatality drivers.

First Quick “Brightness” rule of thumb. If you can even come close to looking at your light from an arm’s length in bright daylight, it is far too weak to be of any worthwhile use. ALL usable Ultra Bright lights are incredibly blinding, retina searing and burning. Think (DON’T actually do) of trying to stare directly at the sun, into a lighthouse, or at your HID high beams for example.

It was all making sense. The reason that people weren’t/aren’t being hit is that drivers had plenty of time to see, identify, and avoid the problem. There is no possibility of a conflict in time and space IF the driver is two lanes away when they pass you.

This has been born out in my life and those of every cyclist I’ve talked to. My wife and I have not had any more accidents or even close calls since we began putting Ultra Bright Flashing Lights on our bikes. Many many many drivers have stopped me/us to exclaim “…WHAT BRIGHT LIGHTS YOU HAVE”… THANK YOU !!!…”

During daytime; I suggest a minimum of three lights backwards and at least two forward for several reasons.

  1. Three (3) is the minimum number of points in space that a (driver’s) brain needs to immediately determine location, bearing, and speed….without a lot of time consuming and confusing calculations. Remember your geometry? # of points to make a Line and Plane?
  2. Redundancy; you never know when a light is going to fail, and it will usually be at the worst possible time.
  3. Battery life; many lights have variable battery life.
  4. Pattern variability; I like riding with lights that all have different flashing patterns to ensure that someone doesn’t get bored/numb/forgetful that I’m there.
  5. Loaners; knowing that the likelihood of a problem while riding with lights is miniscule (compared to without), I have been known to share a light with those without… especially kids, Boy Scouts, etc…
  6. While hitting someone from the front is statistically less a fatality risk than being hit from behind, it will still ruin your whole foreseeable calendar. Riding Ultra Bright front lights is only slightly less important than the necessity of riding Ultra Bright Rear…. Driver’s running red stop signs ahead of you still need their Reptile Brain stabbed….

And I strongly suggest buying/using only rechargeable lights and/or lights that can use rechargeable batteries. Buying and replacing batteries is a time consuming pain, expensive and time consuming pain, hence they are very EASY to forget…and besides, they often leak acid killing your lights.

Once you get into the daily habit of taking your lights off after each ride and plugging them in, it becomes an easy pattern to fall into.

Rule # 5 Drivers APPRECIATE Your Early Warning System…. Ultra Bright Bright Lights.

Take responsibility for your OWN SAFETY and Welfare… No one else is going to.

No one, at least very very few of us ever want to kill someone. And No one, especially drivers, wants to scared to death and shocked to have a cyclist seemingly “JUMP OUT” of nowhere.

Here’s an interesting topic…. Innate Godly/Human factors;

Rather indescribably; Flashing Lights seemingly “cry out”, “I want to Live!”… Human to Human, animal to animal, this is a very strong emotion/instinct/feeling/perception among many living life forms…. Someone has probably done a study on when/why/how this works…? (Please write me if you know of one)…. I don’t… but taking responsibility for your own welfare, and making yourself Highly Visible and WELL Marked, just works…

Repeating, I can’t tell you how many drivers have THANKED me, consistently, for my lights… Some have driven up onto sidewalks and JUMPED out of their cars! It’s actually very interesting to see how often this happens.

Generally now, most drivers just take a Very WIDE berth around us… Because they have ALREADY SEEN us from well over a Half A MILE Away (1/2 mile)… Another example: I take Boy Scouts out for their merit badge rides, and the trailing dad’s in the SAG car JOYfully exclaimed he could see us from a “mile away” (which was probably an exaggeration), but makes the point.

It is extremely rare that we have any issues, any more…and I have heard the same repeated by countless others than ride with Flashing Ultra Bright lights. In fact, I haven’t heard a negative feedback yet…

So, if you follow this advice, the odds/chances of you being (fatally) hit from the rear will be largely eliminated.

However, to make full disclosure beware, we’re not wholly out of the woods quite yet.   There are other very dangerous types of accidents… even if statistically not fatal most of the time… they will still ruin your day-week-months, your body, and your beautiful bike.

  • Be vigilant and on the alert for the bleached brain (and hair) blonde that tries to changes lanes or makes left hand turns into your path, without looking… like almost happened to me just the other day…
  • Stay far away from parked cars. NEVER get closer than 4-6 FEET from a door that can suddenly open and (door) kill you. You may even have to fight for your space. (A motorcycle officer on PCH, once yelled at me and pointed to move over. I politely (honestly, ask my wife) nodded and responded by slowly opening my hand towards him, and then drawing it back in front of me, inviting him to (by all means) lead the way… he loudly scowled something unrepeatable and raced off).
  • Only cross over to the left, from right hand turn and bikes lanes (you’re going straight) AFTER looking several times first. STOP and WAIT if you have to…LET the cars pass. A few seconds isn’t going to change your life, but it may end it if you don’t.   This is the last fatality to mention. A very well known woman cyclist was riding on PCH (W) near Crystal Cove when she was killed. A group of cars were merging right onto a high-speed “highway onramp” when the last driver didn’t see her. He wasn’t cited either. And she is dead.
  • Like above: Don’t expect a thin, white painted line is going to protect you. ONLY after looking several times first, cross over into LARGE protected (by light poles, etc.)hash marked traffic islands at stop lights….. Often, I choose to just pull over and wait… If others are more brave….?… You know the old joke about the old wagon trail scouts (cycling leaders)? They’re the ones with the arrows in their backs… which really hurts… and can end your day(s)….
  • Keep your ears open, and eyes ahead…sounds so simple doesn’t it?
  • If you aren’t very comfortable with keeping a straight line, while turning around in both directions, to see what’s behind, perhaps consider more practice, before riding on the road with others… Too Many rider-rider cycling accidents and injuries occur when someone changes their “line” without first looking back. Just a thought.

There are a lot of excellent rear and front lights out there now… And you need both.

When Purchasing, Consider:

  • Published “Lumens” is only a start. Take out the lights in the store and check them out at a distance. The relative brightness will be quickly apparent.
  • Flashing pattern variability… or the same mind numbing on/off “beat”
  • Are they rechargeable? Getting into a daily habit of charging your lights is critical
  • Beam Pattern. Some lights are very bright with a narrow beam; others have very wide beam pattern “signatures”, but not apparently as bright. Strongly Suggest you ride with both.
  • Mounting options: Can you mount your lights on the seat tube, seat stay, handlebars? Do they have a clip for your helmet-saddle-saddlebag?
  • Mount orientation: As riding is almost always on the right side of the road (we hope), Rear lights should be slightly directed backward and to the left, towards traffic, not straight backwards. I ride the road with front lights on my handlebars, and both forks… (being a pilot I follow protocol and ride with red on the left)…. Front lights have saved me pain a number of times from left/right turners ahead of me.
  • Cost; good lights are going to run $50-$300…each… and I suggest you want/need five to eight for a lengthy road ride.   Too much? Ask yourself again. How MUCH is Your LIFE and physical well being worth? Any number greater than ZERO is a GOOD START…
  • Battery Life. There is a huge variability in battery life and charging time. Best to cover your bases… Some rides may only be an hour and a half, safe for most lights, others might last 4-7 hours…
  • Be considerate to other riders: While Ultra Bright Lights should ALWAYS BE ON if you’re riding on the street… They are blinding to group riders close behind… IF you’re in a group ride, maybe you can ride last in line if you (should) feel more comfortable with all your Rear lights on… (anywhere in the group with Flashing Headlights… Not the most macho position perhaps, but there are advantages in guarding the rear.

Cycling shouldn’t and needn’t be a death sentence

A few years ago, Mark Goodley survived a near fatal collision while riding his bike. 


He’s written a few previous posts for this site, including a review of ultra-bright bike taillights — one of the most popular posts ever on here — and the recent Testing to Destruction

Now he offers a detailed examination of how and why ultrabright lights can save the lives of cyclists. 

Including yours.


SPOILER-ALERT: The secret is slowly getting out that if you (are smart enough to) ride with Ultra Bright Flashing Lights, (sets that are fully charged and meeting a minimum brightness standard) the odds are ridiculously/infinitesimally small, that you will ever be involved in a “hit from behind” injury/fatality accident.1 Wide experience shows that Drivers will keep a very wide berth, and avoid you like the plague.

Now for the inquiring minds that want to know Why?…

Introduction / Abstract

There are over 500,000 cycling injuries accidents in the US every year. An estimated two-thirds (2/3) of the 700 cycling accident fatalities (35,000/year worldwide) are classified as “hit from behind” accidents; where the cyclist had little to no warning. This article focuses on those accidents where the cyclist was defenseless, and did nothing “wrong” (not those killed running red lights, getting run over by trains, etc.).

Most every interviewed driver who killed a cyclist made almost identical statements… “I never saw them”…  As we will see below, this statement is neither untrue, nor a coincidence.

The how and why answers to the “I never saw them” statements are obviously of Great interest, and will be revealed and illustrated in this article… There are scientific and rational explanations for how these statements, repeated (again) by nearly every single (killer) driver are incredibly, both truthful and accurate.

Most importantly, a reliable, affordable, and easy to execute (potential) solution will provide an escape path to avoiding this critical problem. The only real question you will need to answer (to yourself) is: “How much is my/your life worth?”

Let’s assume first that you’re a sane, normal, brain active, and rational cyclist (as opposed to a helmetless macho-man/woman with superhuman immortal powers, invulnerable Kryptonite and 7,500 pound chunks of fast moving steel?) i.e., “You have studied and learned, that man is mortal.” You realize and fully understand that you are responsible for your own welfare (and can’t/won’t “assume” that others will be more concerned about your health and safety, than yourself.)

We might also agree that nothing on this planet is perfect. There are a given percentage of bad drivers that are always going to exist; Whatever their issue, brain dead, blind, deaf, sleep walking, drugged up, distracted, glue sniffing, mentally fatigued, illegal, bleach brained, comatose, and often defensive arrogant @$$%#@holes….

Let’s make the final argument and supposition that the above generality is and will always be true.

That is to say that No amount of DMV/Caltrans fairy dust, driver education, morning coffee, brain transplants, glasses, or better roads will EVER FULLY, and 100% of the time, eliminate Bad drivers from the roads.

Here’s the really scary part. Many of the fatality accidents were caused by “good” drivers as well.   Just as there will Always be bad drivers…. “And it must follow, as the night the day…” there will also be good drivers whom aren’t perfect 100% of the time either.   How can this be? How can good drivers repeatedly kill cyclists, just like bad drivers? Turns out it’s not too hard… Stay tuned below.

To be clear, I have nothing against improving driver-cyclist education; it’s just not reasonable or sane to expect “education” to be a 100% solution, or even close. We need a reliable, sound strategy against bad, and good drivers alike.

This is our not so trivial task… HOW to protect ourselves and cope with this entirely unacceptable situation?   Is “it” beyond our control? If not, What strategies are available to combat the inherent risk to our cycling time on the road?

There is no amount of training or education, that will break through the fatigued, distracted, brain dead, or blind driver; either good or bad. This is just common sense. How are you going to reach any driver behind the wheel on an intellectual or even conscious level if they’re not there already? The answer is obvious and clear. You can’t. It’s Impossible.

Rule #1: IF someone is going to take responsibility for your own Life and Safety, it had better be YOU…it’s Not going come from anywhere else.

We need another tool. One not dependent upon the relative consciousness, awareness, intelligence, clarity, visual ability, or mental (incapacity) state of a driver.

To Reach, Jolt, and SHAKE/WAKE UP EVERY driver, bad and good alike, to our cycling physical presence and location, 100% of the time, we MUST make a HARD strike on an unconscious level. To hope and believe otherwise you might as well self-check yourself into Patton hospital, right now. (link provided below).

Now we are getting closer to an answer. We have to go much lower in the brain, Much, Much lower… Lower than cognitive cerebral conscious awareness.

We have to STRIKE at the lowest, most primitive, and strongest physiologically processes possible. We need to go “for the throat”… Straight to the core Survival Instincts that predate conscious thought. We have to go directly, to the primordial, primitive, primeval, Reptile brain.

Almost 100 years ago, this unconscious REACTION was termed “Fight or Flight” by a scientist named Walter Canon. We need to INCITE this innate, subconscious, uncontrollable visceral reaction that operates entirely outside consciousness and thought.

Getting back to the “good drivers” for a moment… We have to Fully grasp and realize something that none of us wants to admit. Even “good” drivers can entirely miss seeing us and cause accidents. “WHAT?” “WHAT ARE YOU talking about???” “The driver’s Always Wrong…!!!…”… you say….!

We ALL have inherent human perception weaknesses and frailties, regardless of our state of mind while driving.

We have to review and outline a few topics to illustrate the Full extent of this “invisibility cloak” we road cyclists all wear.

First; Human visual Perception and Atmospheric Physics…

  • Lack of our relative movement and perspective; between traffic and the driver. Humans, like most every member of the animal kingdom, detect and identify movement far easier and faster than identifying the source/nature of that movement.  If you’re moving at the same relative speed as the surrounding traffic “pattern”, and or in the same direction, there is every likelihood you will “blend in” and go completely unnoticed; “inside” the driver’s mind, even IF you are clearly in the line of sight and “visible”…
  • Bright, cloudless days, and very dark shadows. Do you know what I’m talking about? No clouds means no diffracted light, no gray areas; only distinct very dark and bright light borders. Do you know the average time it takes for a human eye to fully adapt (Adaptation) from bright light to the dark? Astronomers would knowingly answer 20-30 MINUTES ! So what chance do (any) drivers eyes (the rods) have of making the physiological/chemically time dependent change while driving from a bright daylight area, into a dark shadowed area? The answer is very little, in fact almost none… I rode to the scene of a fatality accident not long ago at the exact time of the accident, two days later. Tall trees on the east, created shadows across ALMOST the whole road. On a cloudless day, like the day of her death, the bright light was blinding, and the shadows, very dark… Seeing into the darkened bike lane line, never mind identifying a cyclist wearing black clothing, was difficult for me. And I was prepared for the physiological/perception drawbacks. She was at the wrong place at the wrong time. Now imagine the shadows cast by buildings, trucks, cars, etc… and you can “see” the problem.
  • Low blinding sun on the horizon. Most all of us have experienced these phenomena. The eyes become overexposed (and overwhelmed) by direct penetrating sunlight that is much brighter in the early morning and late afternoon (due to the reduced atmosphere and scattering). The windshield with inherent flaws creates bright and dark rays making it very, very difficult to see through.
  • Black and dark clothing against black roads… need more be said
  • Dirty or wet windshields and windows – “What is this rusty, dusty, dirty-looking thing over your window? Enough said.
  • Dark tunnels and shadows/overpasses on clear, cloudless, bright days… (see 20-30 minute Eye Adaptation time above). (Remember a decent US Pro cyclist that rode into a dark tunnel,,, without a helmet OR Lights…?… look at how well that turned out…
  • Higher “priority” distractions that forces and takes attention away from road outside (texting/email/phone), sirens, stopping traffic, lane changing trucks, peds, etc.. We will talk about this one in a bit.
  • You photographers/videographers already know where I’m going with this. Our eyes/brains process information pathetically slowly. A VERY SLOW incoming 24 frames per second is fast enough to completely fool our turtle slow brains. Adding to this problem is the ironic placement of our visual cortex at the very rear/back of our brain, the farthest possible position away from our eyes… We (read; drivers included) weren’t designed or meant for quick or efficient processing of visual information.
  • Our minds generally process less than 5% of what the eyes actually see. Again, pathetic but true… Most of the world around us is seen by our eyes, but unnoticed and unprocessed by our minds. I’m not just talking about the ease with which any skilled magician can fool our minds, but in everyday life observations. How much of what is in front of you, do you actually process and remember…? Very little it turns out…. So also for human drivers. Most people are completely (blissfully) unware of the complexity or enormity of the vision comprehension problem.


From Discover magazine2:


The brain must process an immense amount of information as fast as it can, using any shortcuts it can, says Anstis. It has to find a minimum hypothesis to cover a maximum amount of data. So it’s got to use any trick it can. His experiment reveals one of those tricks: We think the brain is programmed to use brightness the way it is in the world. That means shadows are always darker, and light comes from above.


Rule #2. While cycling, like it or not, admit it or not, believe it or not… WE ARE often LITERALLY invisible, to bad and good drivers alike, no matter how alert and conscious they may be. Our presence often just doesn’t register in a driver’s mind. Why not?… is the question, this article seeks to answer.

Rule #3. We MUST find a way to unconsciously BE perceived as a THREAT by the driver to be NOTICED within the subconscious REPTILE brain.

The Reptile brain, first and foremost, identifies threats. We must create Relative Movement and/or change our perspective (frame of reference) relative to the driver. For reasons you are probably already aware, but that will soon be explained.

How can we completely bypass the conscious, perceptual, senses which are too often just plain blind, or dozing off asleep at the switch anyway?…

Let’s get back to the interviewed (killer) drivers’ statements. “I never saw them”. (Where I might also add “… until it was too late”)

The police have a very difficult legal problem here assigning fault to the driver. As I learned from personal experience with the police in my own near murder, a driver not “seeing” a cyclist IS (unbelievably) a valid, legal and very frustrating (for cyclists) defense.

Even though every interviewed driver repeated nearly identical statements, it is impossible for anyone to determine whether this was some mental defense mechanism, (a human rationalization/justification, as many have postulated) or in fact, was visually true. In this case, legally it doesn’t matter. And more importantly, in practice it doesn’t matter either. Dead is Dead.

Let’s get to the core of this legal problem. Wouldn’t it be great for cyclists if this invisibility “defense” variable was taken completely out of the equation?!?   It would seem unlikely, and seemingly extremely difficult to make the “invisible” case/claim when blinding lights are flashing from the bike.

Less than a year after my own near death experience, I mentioned that there were three cyclists that were killed in Newport Beach.   Together, they outline and illustrate each of the issues.

One of them a well-known doctor, was riding with her husband on Newport Coast, in dark morning tree shadows, at the wrong time. One of them, a young woman, had made a right hand turn onto Bayside Dr. from PCH (S). A following gardening stake bed truck ran her over. What is dangerous about this corner is that the turn is largely blind due to a wall and large tree. The driver, like all the others claimed to police, “I never saw her”… which may have been true… The police had no legal choice but to accept his statement, and not cite him. But what if the driver had clearly seen her, and been warned of her presence a minute, and half a mile earlier, Before she ever made the turn?… and undeniably reinforced it, after he made his turn behind her? Would the outcome have been different? Statistics say Yes, absolutely.

Most of you have been tracking where I’m going with this… and some are saying to yourself, “No, it’s too much trouble”… or “NO, it’s too expensive”, or “No, I shouldn’t have to worry about something that is clearly the driver’s fault/problem?”…

OK; good enough…. I only have two questions for you, to Ask yourself.

  1. How much is my (your) life worth? Yes, I‘m absolutely serious. How Much is YOUR LIFE WORTH?… to you, your family, your wife, husband, children, parents…? How MUCH? How much is your time worth? IF you’re hit, at the very least, you Will Very likely be missing work, paying medical bills, bike repair bills, be in a LOT of pain, etc… Isn’t it waaay better (AND A LOT CHEAPER) to avoid problems in the first place, than pay for the resulting outcome?
  2. If you lie BLEEDING in the street, dead or seriously injured, does it really matter who was/is right or wrong?… I’d like to ask every, single, dead, fatality victim, OR their family members, IF they REALLY care who was right or wrong?

Having been there myself, I can tell you definitively the short, quick, two lettered variety answer, for a FACT.

So; now that we have a better understanding of the “perception” issues and problems, for you H. Potter fans; What IS our “defense against the dark arts…”(DADA)… “Unconscious” and blind?
