Too bad transportation infrastructure is completely verboten in America.<p>New York has it grandfathered in (was built before the car era) and New York does not have this problem. The simple reality is that cars don&#x27;t scale beyond a certain density because, well, cars can&#x27;t pass through other cars. Cars work fine for light to medium density but beyond that you must either build trains or stop growing. (Or waste billions and countless hours every day with millions of people stuck in traffic.)
