That picture has the cars bumper to bumper, which is likely rather better than even the self-driving best case. Cars take up a lot of space.
I can imagine interesting and efficient ways to move large numbers of people that involve self-driving vehicles for part of the journey, but for high capacity at reasonable cost and space utilization, feet, bicycles, busses, trains, subways, etc are dramatically better.
