Why no self-driving cars?

DETROIT – In just a few years, well-mannered self-driving robotaxis will share the roads with reckless, law-breaking human drivers. The prospect is causing migraines for the people developing the robotaxis. A self-driving car would be programmed to drive at the speed limit. Humans routinely exceed it by 10 to 15 mph (16 to 24 kph) - just try entering the New Jersey Turnpike at normal speed. Self-driving cars wouldn't dare cross a double yellow line; humans do it all the time.
