Sure, eventually it will be better. But I wouldn't be shocked if bad-weather automatic driving lagged at least a decade behind what they can get away with in Arizona. It's a significantly harder problem, and much more difficult to generate reams of data to test against.

Worse, the risk shoots way up, and people will be much less tolerant of risks that aren't under their control. "Driver Ends Up In Ditch" is never news in places with real winter. But "Google Almost Killed My Family" sure will be.
