Why would it come back wrecked? That's what the camera is for. I would imagine that Tesla will have their own app and when registering you will have to provide a card that allows them to draw a hefty damage deposit if you aren't well behaved. Don't forget it can also alert the owner if there is an issue and call the police if needed.
There are cars that are nicked now. Which has trackers, self alerting police systems and camera's and they're still nicked and never found. Credit card checks are one of the easiest systems to defeat by professional criminals. These security measures are reactive not proactive. Thieves are always one step ahead...
Or you can just decided what hours your car should work and in what geographic locations. I suspect that some of the residents of the dumps around Leeds wouldn't pass the credit check to be able to summon one in the first place.
Again, this is easy for criminals to defeat. They'll have an address book full of stolen identities.
No more than that dodgy banger where the alternator fails, the battery won't charge and has a radiator and oil leak.
The difference being a "dodgy banger" wont have a $15,000 battery replacement requirement. An alternator failure, 12v lead acid battery or radiator leak is an extremely cheap fix in comparison.

I just don't think anybody who invests this sort of money will want it to be used as a Taxi. My dad owned and ran a taxi business years ago. I know all of the stories and all of what goes on and the mileage will also soon rack up, wear and tear will soon take it's toll and you'll be replacing tyres, brakes, ball joints, wishbones, bushes, interior trim, windscreens etc in no time. I think these are reasonable things to replace if you use your car as a "robotaxi" business but as your own vehicle with a limited mileage warranty which includes the monstrously expensive battery, i don't think this "pro" reason to own an EV Tesla that can make you money on the side is actually a "pro"...And for arguments sake, One of his fleet cars, a 5 year old Peugeot 309 1.9d had 420,000 miles on the clock before he got rid of it, which is only averaged at 230 miles a day. So even if you let your Tesla be a "robotaxi" for 50 miles a day which isn't much of a Taxi, that is going to be nearly 92000 miles in 5 years. Suddenly, your 8 year, 100,000 mile battery warranty isn't looking so good and will definitely affect the resale value of your car.
