Two points [[since the name of Mexico City has been taken in vain so many times in the discussion of Detroit transit):

1. Detroit's streetcars have not been in operation in Mexico City for 25 years. They were put out of commission in an earthquake in the mid-1980s. Those cars that weren't destroyed were parted out.

2. Mexico City's extensive "subway" system is in fact a larger type of BRT - it runs on rubber wheels, not rails. I don't think it can steer [[at will), but it does run on a paved network.

I'll leave it to the rest of you to kill each other over the question of whether either of these is a reason to downgrade Mexico City from "real city" status.
