If the future is car as a service, then yes congestion does not automatically get worse, you call an automated car to pick you up, and another one to take you home, it might also mean that more ride sharing happens too
Think Uber carpooling, minus drivers, much cheaper, and short pickup times. Maybe 6-10 person shuttles instead of sedans/SUVs in denser areas. To a car service, moving an empty vehicle is inefficient and a waste of money.
