Owning a car means you get the exact 2 hours you need rather than waiting for the 2 hours a taxi company will sell you. It means you can use the car as 24 hour storage for all the things you keep in your car. It means sometimes you can use the car for way more than 2 hours in a day. You can share the car with other people at minimal additional cost. It means you can live in a rural place 2 hours from the nearest taxi company and not have to pay for 2 hours of additional time as the empty taxi comes to you and 2 hours more when it returns after you're done with it.
For many people a robot taxi is a viable alternative to car ownership, but for plenty of people owning a car is always going to be a better option.
