The auto industry itself; a family will far more easily be able to get by on a single car: "Take Little Joey and Little Suzie to work, drop dad off at the office, go pick mom up at home, then at 3:30, pick the kids up at school, drop Suzie off at soccer practice, and have dad home in time for dinner at 6."

For that matter, shared, scheduled cars on a neighbourhood scale would be pretty great.
