I think that the way you handle malicious actors now is that people know that they have a laser in their eyes. This would be more like "what if someone could just make another car or obstacle invisible to you, and you have no way of knowing it." I agree it is a very rare event, and will always continue to be. But it would need to be handled, and handled in ways other than, "Hi, here's a 100 car pile-up." Similarly, and probably less rarely, you'd need to handle scenarios in which another actor wasn't malicious per se, but faulty to a degree that it was functionally malicious. Of course, we've always had to handle the idea that somebody might be driving a car with bad brakes, and that's dangerous enough, but before now a car with bad brakes wouldn't also make the brakes bad for ten cars around them. I think that's worthy of some contemplation.
