I'm sure there are still issues, but I'd bet they're dramatically more rare than what we see with the FSD beta.

Why would you think that? If they have much better technology, that they are deploying on public roads, why wouldn't they let the public know with easily accessible proof?

Obviously this is cherry picked, but you don’t think a car equipped with LIDAR, imaging radar, more cameras, more compute, and temporally dense HD maps that has focused on the same area for its entire existence would perform better than a Tesla?

I would expect a strictly mapped system would perform significantly worse in an area like SF, where roads and obstacles frequently change. Human drivers are not rigid, they are adaptable, so building rigid AV systems is doomed to fail outside perfect conditions.

They're not rigid - they use the map and fall back to onboard system when it's not accurate. That happens plenty of times in the video I linked.
