Proponents of speed cameras, including The Post’s editorial board [“Slow down, and pipe down,” Nov. 4], cite a reduction in accidents and declare that if you don’t want a ticket, then don’t speed. That simple-minded reasoning fails to recognize the fundamental issue: whether too many safe drivers are being ticketed in the effort to ticket the unsafe drivers.

Suppose the speed limit is 30 mph. Suppose further that a driver must exceed the limit by 12 mph to be ticketed, as in Maryland; that the vast majority of tickets are going to those driving 42 to 50 mph; and that only those driving faster than 50 mph in this particular zone are causing the accidents.

I believe I’m one of the slowest drivers on the road, yet I find it nearly impossible to stay below 42 mph in a 30 mph zone in light traffic on a clear day. The speed limits, mostly at the lower end, are simply not realistic. Does “speeding” mean exceeding the posted limit or driving at an unsafe speed? Those are two different things.

The suspicion that too many safe drivers are being ticketed is what prevents so many of us from believing the claim that the primary motivation is improving safety rather than raising revenue.
