This is like Jevons...not a real paradox at all if you list the full set of parameters....but if you only measure roads and not intersections, lights, speed differences, angle of incline and decline, road construxtion and maintenance....sure...its a paradox....but for common sense people....it makes obvious sense....also..."CAN" is not "DOES"
