I think it's too early to be sure of the effects. A widely available fleet of self-driving cars may help the last-mile problem with public transportation (how do you get from, say, the subway station to your workplace or from the subway station to your house). If this makes public transportation easier, this may decrease miles driven per day. Will self-driving cars reduce the accident rate, and the congestion that results from traffic slowdowns near accidents? Will self-driving cars make better use of less obvious travel routes and avoid bottlenecks in the road network?
