We have a newish commuter rail and surface line here. My only complaints are that it doesn't go enough places, and I want it to have road priority for both the elevated lines and the smaller, surface lines. Both should get dedicated roads where all cars must wait until it passes (save for emergency vehicles, of course).

My other complaint is that our politicians don't have the balls to build an ultra high speed network from southern California to Vancouver, BC, which is what we need. We should just have big signs advertising a state owned 250+ mph train line up and down gridlocked i5 and state/provincial routes nearby. Then, it would get voter approval immediately. Preferably with QR codes attached to the signs to sign your name up on the proposal or something.
