I think highways like the 401 in Toronto prove that the "100 lane" theory is pretty much bullshit. https://en.wikipedia.org/wiki/Ontario_Highway_401 https://en.wikipedia.org/wiki/Ontario_Highway_401 It's arguably the busiest highway in North America based on a number of metrics, even more volume than LA's perpetually busy Santa Monica Freeway. They've been expanding it ever since they've built it and in parts it is 25 lanes wide. It's slammed all the time. Traffic jams at 3am aren't unheard of if they're doing road work and it's slimmed down to half capacity. It was once merely an 8 lane highway, so the idea that tripling or quadrupling the size of a highway magically makes traffic jams go away is so far from the truth. There's a parallel highway running north of it that's paid by tolls which isn't as busy, but only because they can adjust pricing according to demand.
