Spare me.

Most self-driving is done in warm climates, in a circle. These companies are amassing thousands of empty miles on the same streets every day to impress people who don't know any better.

I lived on a branch of the main Google circuit, and often they were the only traffic for most of the day. Even saw three Google vehicles in a line, but two were more common.

What's the value of "self-driving" with no weather, traffic or route variation? PR and regulatory filing stats.
