just something I chanced upon....
police laser radar gets intrference ??
Interesting vid. I could see that would be ok in the UK for laser traps, but I don't think we have those down here do we? All laser still hand held mostly by bike cops? In which case, if I was a cop pointing a laser at a car and not getting a reading, would be suspicious of something dodgy going on. Even though it might be considered legal because it is a parking sensor, I bet they could still ping you for something, like when my towball supposedly blocked my license plate.
