Occasionally around here I'll see a mobile speed indicator that shows the speed of the cars passing by. I usually give them the finger, just as you suggest might happen.

Beck said the devices are sometimes placed ahead of cameras giving drivers advance warning about their speeds.

This would so never happen around here. Traffic cameras exist solely for revenue purposes. I don't think we have any speed-activated ones, but the stop light ones are not put at accident prone intersections, just ones where more people are liable to squeak through, like where the speed limit has just changed.

In recent months a number have been blown up with dynamite, some have been torched, while others have been cut down by aggrieved motorists.

I love it.
