Any of this stuff CAN cause an accident, though of course you wouldn't BE in that situation without roger ramjet closer to your rear end than anyone who hasn't beein introduced should ever be. Legal, I have no idea. In most cars, you can just barely touch the brakes and light the lights without actually applying the brakes. On a related note, 10 and 24 GHz gunn diode sources are relatively cheap, and easily fool radar detectors with a false "speed gun" indication. Laser or pulsed IR emitters for the same purpose also exist. -- > Feel the power of the dark side!
