What is going to stop someone from putting up a sign on the side of a highway that looks like a photo of a red light? Very cheap to deploy and extremely dangerous.
I remember seeing a post on HN (but I can’t find it) where simply flashing such a photo for ~100ms was enough to get cars to come to a sudden stop
