> High speed rail would kill off a lot of shorter routes, but it just doesn't work in the US for some reason. Looking at what is happening in California, cost is the largest issue[1]. The other reason is the US optimized its rail for cargo which it does well. Frankly, I do believe that automated cars with solve the less than 50 mile commute problems better than light rail. I actually am a little optimistic that one of the hyperloop companies will get it together to create a short elevated line that can actually start a new building phase for rail (well, tube) transport. The danger is that they realize they will probably make more money on cargo and go that way. 1) the compromises on speed are going to make for a lot of controversy if it ever does get done
