It makes no sense to copy the transportation systems of a 38m person city, when you're Boise, San Diego, Pittsburgh, Miami, etc. Other major cities like Dallas do not have the density to copy Tokyo such that it makes sense as a model and would be efficient.

The only thing the US should copy Japan on is long distance high-speed rail. The rest can be taken care of by electric buses + a lot of dedicated bus lanes, modest light rail investment and NY fixing its subway. The US doesn't actually need a radical makeover. A large expansion of dedicated bus lanes would fix 3/4 of the problem in nearly all US cities and would be very cost effective. Autonomous electric buses can provide a high volume solution that matches with the modest population size of most US cities.

Within 15-20 years the US is going to reach zero population growth (and the growth rate will be close to zero for much of that time). Shortly thereafter the US population will begin falling permanently. It doesn't need to explode its budgets building unnecessary transportation systems based on copying one of the world's most dense cities for absolutely no good reason.

Sorry but this is not feasible in the US.

Previously on HN https://news.ycombinator.com/item?id=16602151

We can't get our mayor de Blasio to commit to prevent people from stopping on the bus lane in the city (NYC). For example, in Jamaica, I would guess there is a bus every two minutes each way (peak) at Sutphin Blvd Hillside Avenue intersection. It isn't a particularly busy intersection, just an example.

Not just that there are cars parked in the bus lane, there are trucks unloading goods for the shops there, double parked.

The state of NJ says it is unlawful to idle your car for over three minutes. I've never seen anyone follow this rule. We might as well get rid of laws without enforcement. Who are we kidding?

Making a bus lane without enforcement is just wasting money to paint a lane. How do we enforce it? The only way I see viable is to allow bus drivers to write tickets to anyone blocking them (even for thirty seconds) in a bus lane (buses should definitely be equipped with multiple dash cams) and give the bus drivers the ticket money.

San Francisco Uber drivers are deathly afraid of cameras mounted on buses that issue tickets for being in bus exclusive zones. That works quite well.

Downtown Seattle has bus lanes that are well enforced. It's feasible in the US.

Assuming zero immigration?

Immigration isn't a constant force of nature. It will never go to net zero, but who's to say that as opportunities improve elsewhere and fertility drops, immigration might not drop to replacement level?
