The roads have been given extra lanes, and the total possible throughout of the road has increased. As a result, car manufacturers have decided that they can use a cheaper manufacturing process which makes slower cars. But when anyone complains, they point to the additional lanes and say ‘but the number of cars that get from point A to point B has increased, even if each trip is slower.’
