I think it’s established fact that you can’t reduce congestions by adding more lanes and roads. Not because of bad road design but because the amount of cars will fill up those new lanes. So saying ‘cars cause congestions’ is pointing at the fact that regardless of how many roads or lanes we have the will be filled. Hence roads aren’t the problem, but cars are.
It applies to smaller cities as well as fat as you I’m aware, not just mega cities.
