Regardless of whether private Tesla owners end up participating in the robotaxi market it does seem obvious that self driving taxis are going to be huge. Waymo and Cybercabs are growing quickly and will almost certainly completely dominate the market. Why would you ride in a Uber with a stinky driver (and pay more) when you could ride in a self driving taxi without a driver for cheaper?
We should set a safety bar, and any method of achieving that bar should be fine. I'm fine with "N miles driven per injury."
It's not stupid if it works.
My guess is that you have ridden in an Uber or Lyft before and were comfortable enough to rely on their eyeball based system even though they weren't able to measure the distance to objects.
Regardless of whether you personally trust a camera-based system, the data do seem to show that it is possible to build a camera-based self driving system and have it be safer than human drivers.
What data? I don't really trust Tesla to release accurate data.
