Bullet trains never crash?
Bullet trains are not practical in the US --- anyone who proposes them either 1) doesn't understand them, or 2) builds them and is trying to get rich by screwing the public.
Just out of curiosity... why are bullet trains impractical in the US?
Bullet trains are effective in small countries - the distance between ticket selling locations is small. Thus, they are able to sell tickets for shorter runs, thus driving down the cost-per-mile to make it cost effective. Using bullet trains to go from LA to Chicago, or Cincinnatti to Dallas just isn't economically feasible.
In addition, using the bullet train presumes a robust public transportation system in the cities. We don't have that - anywhere. When you arrive at the station, you're still 15 miles from your office. I was in Southern California when they put commuter trains in for only gazillions of dollars. I tried to use it --- the best schedule I was able to arrange was 4 hours 20 minutes, 5 train changes, and the closest stop to my office was about 4 miles.
Small countries like China? Try again.
Not a problem ... if the government is willing to subsidize the costs. This is NOT a profit making business. In addition, China has little or no private transportation infrastructure. Most people don't own cars, and can't get from one city to another. Thus, the government pays for railway. You willing to do that?
China has about 9,000 miles of bullet trains. That's a track from NY to LA and back, and a link to Seattle. That hardly qualifies as significant. Oh, by the way, they had 2.49 million passengers in 2014. Do you seriously believe that we can create that kind of traffic?
I quote the London Financial Times, 2011-04-14. "Concerns about HSR safety, high ticket prices, low ridership, financial sustainability of high-speed rail projects and environmental impact have drawn greater scrutiny from the Chinese press."
These are the very elements that make them impractical.
