Sometimes, when there are no cars coming the other way, I veer out of the way of speed bumps in the parking lot. Other times (when my wife isn’t in the car), I just go over them at normal speed (15 miles per hour, of course).

I’ve rarely stopped to look at the speed bumps themselves. I took the picture below of a speed bump’s leading edge (the part that takes the first hit of vehicles’ tires). This one has taken its share of abuse.
