This is a nice feature, I'll give you that, especially when you're in a new place. Social conventions of driving vary a lot, and "hey there's a cop ahead" is a good reminder to check yourself.

I'm no speed demon (it's just not worth it IMO). But, in Chicago you can do 10-15 over on an interstate and nobody cares. The cops are doing 20 over. If I saw someone actually doing 55 on the Dan Ryan I just assumed they were stoned, and I'm only half-joking. Elsewhere around the Great Lakes, it was more like 5-10 over. Meanwhile, in the Bay Area the flow of unimpeded traffic is usually only 0-5 over.
