They’ve wanted to start a commuter service between Ann Arbor and Detroit for a while now. Even on existing track they can’t fund a demonstration of the service. The best they can promise is a cost of around $70 per rider for what is a 35 to 40 minute drive in traffic. On existing rail it will be anything but high speed and a person can drive the distance faster and do so without needing a shuttle from the train station.
I myself seldom go more than 30 miles from home and prefer to drive when I do.
You want to build high-speed rail and a station or two? Cue the nimby's.
