Ideally: Travel point-to-point, rather than constrained by roads, turns, intersections, all competing with similarly-constrained traffic. Congestion en route would largely go away (although we would probably adopt "lanes" of travel analogous to what the airlines use) and would be replaced by congestion at popular destinations (again, much like the busiest hub airports). I think a more feasible variant of this is a small platform on which the pilot would stand or sit, or from which s/he would hang, lifted and driven by the equivalent of multiple battery-powered drones.
