Basically the 95 Corridor (Boston to Washington D.C.) is accessible via public transportation and a few isolated cities are manageable (SF, Chicago, Portland, etc) within proximity to the city but the rest of the United States Requires a Car... and yes it sucks. Ergo, Amtrak could be useful depending on where you are... otherwise you'll want to get a personal vehicle. Are the ratings real? Yes... but they're also not real.
