Car Denial of Service?
So, shining a red light at a Nissan for long enough from the side of the road will make it think it's going through a red light and slam the breaks on of the other cars around it (assuming they have the system fitted)? Cue kids playing with torches and red gel filters. Sounds like a disaster.
Mind you, so was the shed of an X-Trail I bought without this system on board :)
Paris, because her natural habitat is around red lights.
