Eh I can't find citations right now because I am trying to be productive but modellers and people who study this argue that a lot of traffic is caused by sub-optimal driver behavior. Specifically issues with merging/ and phantom waves that build up and cause phantom jams. Accordingly people think the self driving cars will not be susceptible to this -> less traffic(?). I do not know I agree with these claims since I haven't looked at the math but I am not so sure self driving cars will lead to "much worse" traffic than human driven cars.
