I certainly worry about the usefulness of the M-1 line. My fear is that it's going to be another People Mover, which I believe is the most expensive public transport system in the US (if it can even be called that). It's a joke, and it's existence is a source of ridicule instead of pride. It also has the unfortunate side effect of being one of the few counter examples of the axiom that public investment in transportation is good for the local economy, giving fuel to critics who are against a regional rail system. Maybe M-1 will work. I'm skeptical, but I hope for the day when I'm proved wrong. I still have yet to find a good answer to the question of what need it's filling. If it's a showcase for what light rail can be, with the hope that it will eventually be expanded, then I sincerely hope it's a wild success. The investment happening along side it in Detroit at the moment is encouraging, as a $2bln development was just announced last week. Hopefully the pump is primed and the time in history is right to see some real change. Given the history of the region, however, one can be forgiven for not being overconfident.
