Waymos crash less than human drivers

The issue with self-driving is (1) how it generalises across novel environments without "highly-available route data" and provider-chosen routes; (2) how failures are correlated across machines.

In safe driving failures are uncorrelated and safety procedures generalise. We do not yet know if, say, using self-driving very widely will lead to conditions in which "in a few incidents" more people are killed in those incidents than were ever hypothetically saved.

Here, without any confidence intervals, we're told we've saved ~70 airbag incidents in 20 mil miles. A bad update to the fleet will easily eclipse that impact.

We're probably well past the point where removing all human-driven vehicles (besides bikes) from city streets and replacing them with self-driving vehicles would be a net benefit for safety, congestion, vehicle utilization, road space, and hours saved commuting, such that we could probably rip up a bunch of streets and turn them into parks or housing and still have everyone get to their destinations faster and safer.

The future's here, even if it still has room for improvement.

I'd think congestion would go up as AVs become more popular, with average occupancy rates per vehicle going down. Since some of the time the vehicle will be driving without any passengers inside. Especially with personally owned AVs. Think of sending a no-human-passenger car to pick up the dog at the vets office. Or a car circling the neighborhood when it is inconvenient to park (parking lot full, expensive, whatever).
