Depends heavily on where you are.   In Canada, for example, "bike season" is often very short, so bike lanes are a great way to murder a business district.  The lanes, will only see a handful of cyclists per year (the majority of cyclists preferring the 2-lane road 100m back), but it will eliminate street parking, diverting shoppers to the big box stores which are build on land, coincidentally, leased from the city councilor's brother.

Is the problem bike lanes in general, or poorly planned bike lanes?  Poor civic planning of any kind hurts commerce.
