> If you look in to why Waymo started “full self driving” in Arizona and, now, San Francisco it’s because the cars cannot even drive in light rain and the entire fleet is garaged with even mild inclement weather. We are still lightyears away from actual self-driving cars that can manage variable weather and even slightly-unpredictable terrain.

It rains in SF and there’s even fog… The fog’s name is Karl by the way. It’s also an old coastal city that doesn’t have a sane layout that you might expect from a test area like Arizona. SF is not an easy challenge and there are plenty of self-driving startups that have tried there and failed.
