Good point, although the plan is not that we should all stay home, it's that we should have high speed rail to replace a lot of trips that currently happen on planes. Personally I'd much rather take a fast train from san francisco to LA than a plane. Back when I lived in NYC I had to go to Boston and DC for work several times a year. Some coworkers thought it odd that I would take the train, but time-wise and cost-wise it made sense.
