Once you don't have to pay a human driver salary, it won't make sense to use such large and expensive vehicles as buses.

Removing the driver does not change the efficiency of mass transit. In fact, I’d think you could run even more buses on the same route by removing the driver.
Also the amount of space per passanger the vehicle takes up on the street is smaller for a larger vehicle.
The price of a bus is roughly 10x the price of a car.
The average number of passengers in a car is about 1.5.
So the average number of passengers in the bus has to be over 15 to be more cost-effective than a car. 15 passengers is far from full. And it is on average, not most of the time.
For the space the passengers take up on the road, it is even more extreme. Take a look at how far apart cars drive on the road. About one or two cars take up the same space as a bus that can carry dozens of passengers.
