My employer (the government) just installed new GPS into the cars that supposedly tells them when you're speeding IN EACH SPEED ZONE. Does such a thing exist? we think they're trying to scare us.

They say it tells them when you’re idling in place for more than six minutes (which is illegal in our county) when you go outside the county lines, and when you speed anywhere, not just over 55. Does such a thing exist? It seems that each town would have to somehow install something that tells the satellites what the speed limit is for every road, which seems improbable.

Supposedly we will get written up and if we keep doing it, we’ll have our driving privileges suspended. I can see it telling them when you exceed 55, but i can’t see it telling them everywhere, exceeding each speed limit on every road.
