I don't think you understand the magnitude of change.
Just like Uber is bigger than the entire taxi industry was, because it didn't just take over the industry, but it expanded it, this will be the same. But an order of magnitude bigger.
There will come a time when Tesla, and others, stop selling cars to the public. Because they can just take their entire manufacturing output and make them robotaxis. I mean, they will be producing 5 to 10 to 15 million cars per year that are never sold to individuals and are exclusively used as taxis. There will come a time when a majority of vehicles on the road are taxis. There will be no wait, not any longer than it takes you to walk out the door. And the taxi will be cheaper than any car you own, even if you were to buy a 40-year-old combustion engine and fix it yourself.
Meanwhile, all the privately owned cars can be used as taxis anytime The owner wants. My car has self-driving. I will be able to send my car out as a taxi 8 to 20 hours per day, and still retain full use of it. It will charge itself. And it is still mine. But it will be a money generating machine, not an expense.
When these things can be operated for under $0.10 per mile with no supervision, everything changes.
Uber was just a better version of taxis. This is a completely different thing.
