Eh, if there was an automated taxi service that was really cheap (since there isn't a driver) I have a feeling that the need for individuals to own cars would go down.
There are people out there that can't drive or that have limitations on driving that this could help, and in the long term it may be cheaper to pay for a service rather than own a car which needs maintenance, costs generally 20k+ new, and is a liability from a financial view.
