If I'm suspicious I always call 911  done it 2-3 times in my life. Like getting pulled over by an undercover police car. I'll use hazards and slow down until I reach 911 but I'm not stopping until they say it's one of theirs. Hate undercover cop cars to begin with.

People use the term "undercover" way too much when they mean unmarked. My father was a homicide detective with the county and since only uniformed police drive black and whites, he drove a dark green crown vic, he was at no point under cover.

Plus, no actual undercover cop is gonna do something as stupid as pull someone over.
