Maybe we could convert cars to maglev, that go super fast floating above roads and pedestrians but cars follow 'tracks' and convert to normal street when nearing destinations. Truckers could have 'ports' that maglevs hook up to so trucking and commercial vehicles wouldn't need drivers to 'take over' in local environs.
