All that for 7.7% of passenger traffic seems a bit wasteful given the cost of construction in the modern US. The boondoggle that is the California "High Speed" Rail multiplied by the lower 48 states a few times over does not at all seem worth it versus other infrastructure improvements that need to be made.

1) it doesn't have to be a boondoggle, but it generally is because of US citizens' love of cars

2) 7.7% is a nontrivial number, and I expect it to increase if transportation became more accessible
