Right now we have parking lots full of cars without people in them. Seems like sitting ducks for bored people with rocks, right? Why would anyone have windows in their house if someone could just throw a rock through it? In reality, people are usually well behaved. The fact that self-driving cars have cameras and sensors like mad means that even fewer people would risk the jail-time they'd get by throwing rocks at them. The idea that suddenly once cars are driving without people there will be a significant enough uptick in vandalism that it will deter cars from driving around is absolutely laughable. If this were a realistic threat, we wouldn't have parking lots now.
