I can't do that with Lidar, (or at least, not effectively) because the beam does not disperse like a radar signal does. Laser beams to diffuse over distance, but compared to a radar signal, the diffusion may as well be non-existant.
Sometimes I'm more relaxed about speed when an officer is in front of me (if there's no rear antenna). I never considered the possibility of shooting the mirror, heh. I'll have to remember that trick.
As for lidar, I've seen active lidar jammers on the market. They are legal because the spectrum is not FCC-regulated. Those jammers actually work, but since the dispersion is so narrow it, mounting location is important. The grille is the only place that would give you a fighting chance. Personally, I'd save my money and take my chances, but if you want to go all out with the electronic warfare...
Lidar is brutal, but it has limitations. The biggest is that the enforcer has to be stationary, so traps are usually in plain sight from a ways off. If they ever perfect moving lidar, I'm ending my speeding career.[/b]I don't know of any actual Lidar jammers (not snake oil). In order for that to work, you would have to know exactly when and from where the officer shoots the Lidar gun. I suppose when they invent time travel, that will become possible... :rolleyes:
