a low speed limit

So, recently, I've come across some funny facts that have to do with the low speed limit a long time ago. For example, Teddy Roosevelt was the police commissioner of New York City in 1895 when he formed the "Bicycle Squad." Members of the squad chased down speeders who exceeded the speed limit of 8 miles per hour. Another fact, the first person to be killed by a car (in it or by it, I can't remember)... well, how to finish that sentence, I don't know, but the car was going a very, very high speed of... wait for it.... wait for it... 4 mph!
