That's great. I'm glad they're good enough to drive in the southwest. But Waymo cars performance in SF cannot be implicitly extrapolated to non-SF environments.

Try the same thing in a place with winter on a normal suburban city road. The road edges and evolving swarm-defined lanes have little to do with the absolute GPS position of the unobscured lanes and edges. An all the road makings are often obscured for weeks at at time (or longer). The road surface snow looks just like the road edge snow. And it's a semi-permanent slippery surface. There are a lot of challenges left in non-cherry picked regions before autonomous driving can be said to "outperform comparable human benchmarks" without this qualifier.
