Is there anything to indicate that autonomous vehicles would even help with congestion? Why would they? If anything more people might take them at the worst hours (because it would be less annoying for them without the stress of dealing with bumper to bumper traffic). Cheap, reliable, dense public transit with diverse "last mile" options is clearly a much better choice from the congestion, efficiency cost point of views.
