I don't see any way around it. Once you have the tech to prevent an automobile from exceeding the speed limit in a school zone it's obscene to manufacture cars that respond only to the input of the driver's foot on the accelerator, with no other considerations. At some point, "I have decided to drive 130 mph down a residential street, because that's what I've decided to do in this exact moment and I have a right to be in control of my own car" just isn't good enough. You have all these other inputs and, what, you're just going to ignore them?
