The advantages to self driving cars being used this way are even better:

- people driving don't have to take time to find parking lots

- the cars themselves don't need to be parked in the city, freeing up space

- depending on how many people are traveling together and what they are transporting different sized vehicles can be used

That being said: the most efficient form of transportation any human can do right now is the bicycle. It is fast too. During rush hour I am faster than car, bus or subway on my commute (German city) and as I am sitting on the computer for long periods anyways, having a little movement is great. And for weather there is appropriate clothings.
