And how much did that cost? You can get around Tokyo on the subway system for $5 for an entire day, and it's a profitable system that largely does not rely on taxpayer subsidy.

And how fast would it be if Tokyo and Taipei's trains weren't handling 80% and 40% of trips, respectively?

If you reduce Tokyo's 80% trip usage rate down to 5% like many American cities, that means for every other car on the road in Tokyo you'd now see 5 cars instead. How's that Uber ride looking now?
