If a thousand people try to go to work at the same time, the car being driverless or not will not result in less than a thousand cars being driven, and the number of cars in the road is the biggest cause of congestion.

However, a bus can carry a hundred people comfortably. Ten buses instead of a thousand cars results in much leas congestion.

Well, not exactly. The good thing is that automated, centrally booked autonomous systems can run pretty good car pools. Sure human drivers can do this but it's just not as practical. Not at all. So it's possible that those 1000 people might be served by 500, 300 or maybe even 250 autonomous cars.
