There's been some talk lately about these new police `radar' guns on rec.autos (I'm not sure if the term radar applies here). Anyways, what I want to know (from you laser experts) are: The danger to drivers' eyes of getting laser light fired at them, The ability of using IR detectors to detect the laser light, The reflectivity of cars (ie modern cars with lots of front and rear reflective plastic lenses vs older cars without them) The jamming capability of car mouted IR diodes and/or incandescent headlights BTW, I'm referring to the new radar guns which use laser light instead of micro-wave radiation to determine a vehicle's speed.
