I think you are wrong. I think accidents will actually decrease with driverless cars. As any cop will tell you, 99 percent of all accidents are caused by human error. Besides, driverless cars don’t have egos or tempers. They don’t take it personal if they are cut off or honked at. They will slow down and make adjustments. Humans drive aggressively. Driverless cars will drive submissively.
Speed limits are set artificially low to generate revenue. So in a robo-car world will the powers that be raise them up? Will they let go of a major revenue stream? I am not really interested in putting around county roads at the posted 45 MPH.
