100 cars driving around the tech capital of the world is not even close to the scale many people imagined 5-10 years ago though.

No, but the last five years of progress have not been exponential, which is the whole point of discussion with GP. A major breakthrough could see it 99.9% solved and adopted at scale, but until then it could be a slow grind for every 0.1% of progress.

Driving frequently in a large areas of a busy city without a safety driver is insane progress. Just lots of hype-men like Musk (and earlier Jensen) made wild promises.

It should be noted this service is only available 10PM-530AM, and only in the less traffic-y areas of SF: no downtown/market, mission, etc.
