I see from the responses that many people are still hopeful, citing driverless Waymos buzzing around in places like Phoenix, where it's always summer.
Sorry guys. When I see one that can deal with Boston in the winter I'll begin to believe it.
Actual driverless cars would require, for starters, full AGI, which is impossible because human intelligence is not digital. Then you would need sensors capable of delivering representation on a par with what we humans get. We resolve the ambiguous inputs into something we can act on then act immediately because latency = death, just as it did when our biggest problems were smilodons and cave bears.
