radar doesn't see around corners. At any rate, would have to see some evidence that it can handle the worst of The City before I took a ride, like the incessant construction, steel plates on the road covering new holes, taped off lane changes, resulting traffic jams where merging is happening and so on. It's a really difficult environment for a human and I've never heard the claim yet that self-driving was better than humans.

Cruise publishes a lot of their AVs driving around SF for over an hour. In a video from their YouTube channel [1], at around 22:29, you can see exactly how they handle a steep 4-way intersection. You can also see on the above visualization what objects their system sees as it is performing the maneuver.

The evidence is easily accessible - next time I suggest you just research a little bit first instead of going straight to speculating.

Where was I speculating? I expressed skepticism and said I'd have to see some evidence. You provided some and I'm still not convinced from this. Those are fairly mild hills on wider streets in bright sunshine. But now I know where to get more evidence, so thanks.

Edit: The Cruise CEO kvogt says it's geofenced. That's what I thought.

In a few years our next generation of low-cost compute and sensing lands in these vehicles and our service area will be large enough that you forget there is even a geofence

The car handles a lot of those situations on its own, but can also call remote operators if it's confused, who will instruct it on how to proceed.

As to the earlier question about intersections at steep streets, I would guess they just avoid the most difficult blocks. But they do also have superhuman vision, since they have lidar and cameras on the roof of the car (higher vantage point than a human).
