Wow, surprise surprise, a speed trap that is no longer there is no longer working. I bet it would be a different story for a fixed camera speed trap that is well signposted.
I've found those just cause people to brake hard before them and speed up after. If they become well known, they make people speed even more before/after, as it's not expected to have another speed control measure so close to a trap.
In the UK fixed speed cameras are actually painted bright yellow, for the sole purpose of making them more visible to drivers. The reason being is they are positioned in places where you want to force the traffic to slow down for specific safety reasons (merging of two lanes, exits etc). They are not meant to change the behaviour of drivers on the road as a whole.
I don't know about the US, but I think we'll have on every major road in 10 years here in Australia.
They also do this thing where there are two sets of cameras, and if your average speed is above the limit between two points your in trouble. At the moment they target heavy vehicles, but my guess its only a matter of time before they target all vehicles.
Virginia? If not, we do too. I think it's 80mph OR posted limit+20. Either way is an automatic reckless driving ticket (which can be criminal, with arrest and impounded car).
