L.A. county officials are opposed to the idea of a bullet train to Vegas. Why? Well, they're not ready to encourage residents to leave the city on the weekends and spend their money elsewhere. I think it's only a matter of time before it'll happen though. As for the rest of the country, I don't think it's practical since the U.S. is so large. Even the fastest train would take at least three times longer to arrive at a destination than an airplane...and who the hell is going to want to spend 24 hours sitting on a train to go from Boston to L.A. when they can do it in the air in seven?
In the mean time, I suppose the Obammer thinks we should have a massive government program to mandate tire pressure (paid for by windfall profit taxes on air companies). You know...considering the fact that gas prices havet jumped 150% in the last six years because drivers got lax on their tire pressure...
