Radar Detectors!!!!!

I came across a very interesting thing in the net... Radar detectors!!! Basically these are things ppl can install in their cars to detect speed cameras. These things are supposed to let you know in advance if there's a speed camera ahead so that you can slow down immediately before your car is caught for speeding. In the US, these things are illegal in only 2 states! In the radar detector reviews website, there are reviews about these things. Helpful website if you want to know more.
