I guess I place a premium on safety over land use and congestion.
I also suspect any future congestion and land-use problems will get better after an initial dip. Urban living becomes more desirable as city parking lots disappear.
If roads are used exclusively for self driving cars, this would probably improve traffic flow. Robot cars multiply current highway and city street capacity by coordination. They can smoothen traffic flow due to hard braking, and drive much closer to each other.
