Liability? I'm afraid you don't know how liability works. UPS often doesn't even have to pay for the accident, when they blame the driver. Blaming the driver is an internal company matter. They do that even when the other insurance company paid.
I literally said that edge cases were still being worked on. Tesla has trillions of hours of video and is building the best artificial intelligence engine that will come online this year to help translate the hard cases into better automation. Stuff can be solved. A supercomputer called Dojo will solve it.
This is still a bunch of horses laughing at the Model T saying, "Look how much it breaks down! That will never replace us! It can't even go up a hill!"
As for the extremely silly objection by somebody about trash trucks, the technology to do this "in the wild" or in a geofenced area is literally being rolled out professionally just now. It's a profoundly stupid objection to say something hasn't happened yet. It just started. But the pace is beyond what you can fathom. Breakthroughs make a snowball tumble very fast.
There will be driverless, electric robotaxis operating in every major city within a few years, and charging less than it costs you to own a car. Mark it.
