well the one issue that should be obvious to all is that self driving cars suffer worse from the problem people suffer from, signage and markings on roads is still either incomplete or in some cases in error. People screw up every day driving and the lives lost is very high but going by how my Tesla drives I am going to say impede traffic by slowing down. My car does slow down, safely, when it gets confused or contradictory feedback, and I am curious what the in beta FSD software will do. Their new technique looks vastly improved. Traffic aware cruise control which many cars have along with limited lane keep assist can go a long way to making the drive safer but many don't use TACC except on highways Look at it this way, its coming. However it is all one sided because again I emphasize, we need better and more consistent signage and road marking. US wise, the HOV and Express lanes are probably the most perfect use case for self driving cars. Get into the lane and it should be hands off until exit.
