If you look at the map, downtown Detroit is the center of a spoked wheel, with Michigan Ave. going west, Grand River going NW, Woodward going North(ish) and Gratiot going NE. While the people mover was going to move people around downtown, there were going to be lines going along those spokes outwards into the suburbs.
But federal funding for cities and things like that quickly dropped off during the Reagan years and Detroit suffered hard.
Today they are building a 3.3 mile light rail track along Woodward (the main street of Detroit), going from Downtown to about the center of the city. People wonder why this isn't going all the way to the suburbs--at least to 8 Mile--and many say it's simply another project destined to fail: a People Mover 2.0.
However, the People Mover is good at what it's used for. It's convenient to go to hockey games and it's much better than walking during the winter.
