I highly doubt self-driving is going to reduce congestion. Self-driving makes driving more convenient & useful, so people are going to use it more.

And it is also inefficient because it is used in cars taking 4 passengers max so it can not really scale.

But if a bus, a tram or a train would have a self driving... but that smells like communism to our techbros from Silicon Valley.
