Having a robot car pick me up at my house and drop me off at work is far more efficient than me having to drive to a train station, wait for the train, switch to the subway, wait for that train, then walk to work. It could be picking up an dropping off people on the way, it doesn't have to be a solo vehicle. If you think about congestion as the number of people in transit at any point, this should reduce it. It would also reduce concentration because you wouldn't have people clustering homes and work around transit stations, it would be more spread out.
