Police car that self drives
It could be equipped with cameras and video cameras and sound recorders. And it would drive around and record the behavior of drivers around it. And if it picked up that someone was driving faster than the speed limit that would follow them and get their tag information and cite them.
If it had a situation occur in year it could be the first officer on the scene. Pull up and start taking video of criminals in action. So that when human officers showed up they would have a record of what happened rather than getting there too late as is often the case.
The cameras would only activate when there was a suspected criminal activity occurring. It could also activate stop signs and traffic lights and that sort of thing.
And they could even be electric and drive around all day until they needed to return home and recharge. I like a Roomba.
