Couldn't you just shoot human drivers from a distance with a sniper rifle? I don't see why everyone is scared of new technologies being exploitable. Our civilization is built in the basis that most people are not assholes most of the time.
Investigators arrive at car crash sites far more ready to consider them accidental.
Not to mention I could have a rifle by the end of the day in my state.
Meanwhile lidar spoofing attacks are likely going to be far harder. You need to obtain expensive (and probably illegal) equipment, and have the technical knowledge to use it. I don't know what the range of such an attack would be, but I don't think it would be better than a rifle.
The FBI successfully arrests and prosecutes those who do. Why would this be any different?
