Ditto here. Actually, the new ones are nastier. They don't work at a single spot - that just causes stop/go behavoir. What they do is record ALL the number plates into memory as they pass Camera 1. When the same plate passes Camera 2 - several km up the road - it checks to see how much time has passed. If too little time, then the two images are sent for a human to check. If they're the same car...speeding offence. > >http://www.autoplates.com/photoshield/laser-shield.htm. > > > Those are SO illegal here - big trouble if you're caught with them (or > with radar detectors, and they have radar detector detectors).

The radar detector thing can be beaten if you're careful. In the UK, OWNING one isn't illegal. Using it to avoid radar guns IS. And there's a few tricks..anyway...
