All green on a large car intersection: https://www.youtube.com/watch?v=eIqCei97M74

Intersection designed for bikes https://www.youtube.com/watch?v=2RQrKP9a0XE

People on bikes naturally avoid and communicate with each other non-verbally.

100 lanes sounds like a massive exaggeration but is actually undercutting it lol. It’s insane how space and energy inefficient it is to transport that many people in individual cars.

The yamenote line transports 5 million people a day

The Katy Freeway transports 219 000 cars. Let’s say that’s 400 000 people. (pretty generous I think, most cars are just one guy driving to work)

You would need 5 million / 400 000 = 12.5 Katy freeways.

That would be 12.5*26 lanes =325 lanes!

I was there as a tourist this summer and it was fine overall. Middle of the day there were often lots of seats open but early morning or around 6 you had to stand but it wasnt bad at all. No pushing or anything.

The Tokyo metro system is amazing, I rode like 50 trains all over the city the entire day, and it was really pleasant the entire time
