California is looking to build a high-speed train system from San Diego to Sacramento, with stations in Los Angeles and in San Francisco, and all along the route. I note that they expect the system to cost only $40,000,000,000.00 (40 billion), and that it will be 800 miles long.
California thinks it's worthwhile to spend $50,000,000.00 (fifty million) per mile for high speed rail. That's an astounding amount of money, but it's a necessary step for connecting their communities without using automobiles. California is an incredibly long state, and the only realistic option now is driving.
California, at least, is planning for the future.
