I look forward to reading that. As I understand it there are several different approaches being taken. I’m not suggesting that AVs will be ready to for every driving environment. But they will (and are) ready for cities without snow, geofenced to restrict them while we get more time to learn more. The pace of learning is really what tipped me from thinking it would take a very long time, to believing that the first pilots are just around the corner (this year already, and more larger ones next year), and that from their improvements will happen quickly.

Your reference about the 25mph is confusing. I was in a Google car on a highway going a lot faster.
