Once automated cars are in place, companies can simply become dispatching services for privately owned cars. Don't want to pay for parking in the city after your car drops you off at work? Let it drive around town and make money for you, then pick you up at the end of the day to drive you home. Then, it can pickup your neighbors as they leave the local bar at night, and it is ready for you, charged up in the morning.
The taxi industry has at most 5-10 years left in it. They should be petitioning that dispatch services need to own taxi medallion rights in order to dispatch for the next 10-15 years, so they can at least recoup some of their investment on the medallions by selling them to the new dispatch services.
