That was a waste of an article. There's a saying: the simplest explanation is often the correct one.

Cars, the reason there's traffic is that there are a lot of cars in NYC. That's it. This isn't hard. Why is that car stuck? Cuz there's a car in front of it. Why is that one stuck? Cuz there's another one in front of it. Why is that one stuck? Cuz it's stuck at a light. Why do we need a light? Cuz cars are fast, take up a lot of space, have horrible blind spots, and you have to control their movement (we did not have traffic lights before cars).

So the answer should be pretty fucking simple, but ppl refuse to accept it: reduce the number of cars and physically limit their speed (narrow rows, car-free areas, bumps, chicanes, governors) and size (bigger cars take up more space and lead to more congestion).

EVERY OTHER REASON given is just someone trying, and failing, to come up with an explanation that isn't "cars". We've tried every single other fucking solution over the last 100 years. It's time we wake up and smell the roses.
