I am the kind of person who would get a tesla and I would never want to deal with the inconvenience of lending my car to a public fleet so it could get fucked up by drunk people.
Also how does the car know if someone throws up in it before picking up another passenger?
I'm a strong believer in self driving cars but don't think car ownership will decline meaningfully. Having your own self-driving car still brings you home when you're drunk but without waiting in the cold (or surge pricing if the bar just closed).
Camera + microphone + vomit recognition software.
Obviously the market would adjust from current taxi rates, but this is based off of the following rough estimate:
20 hours per day of you not driving * 30 days * 11$ avg taxi take-home per hour[1] = $6600

Owning a car is (for most) not just a necessity, it's an expression of freedom. Being reliant on a car sharing app is not ideal for everyone, esp. families.
Also I don't think it would last very long driving around 20 hours/day every day.
It would be like airbnbing my apartment. Huge pain in the ass all the time with maintenance and dealing with other related issues.
