It would be fun, then the police would show up and arrest the people who did it using camera footage from the automated cars. Most people are good people, and the ones who aren't already fuck with the road network now causing all kinds of chaos.. throwing bricks from bridges, ripping the copper out of traffic signals, but it's relatively rare because most people aren't trying to ruin everything at great risk to their freedom. I don't really understand why automated cars would be a huge change of affairs.
