I hope Detroit's physical infrastructure doesn't undergo the problems New York City's did in the late 1970s and into the 1980s following its near-default in 1974-75. People who travel in NYC are still feeling the effects created by years and years of deferred maintenance (i.e. as simple as repainting to keep rust from forming) on some highways and its subways. For example, Manhattan once had an elevated, limited-access highway running down the entire west side. But thanks to bad maintenance, part of the roadway collapsed and nearly all of it had to be torn down, leaving a street-level road with traffic lights causing lots of congestion. In 1988 the Williamsburg Bridge had to be shut down for 2 weeks after corrosion was found in a floor beam. For 20 years starting in the mid-1980s, some subway tracks on the Manhattan Bridge have been closed so the bridge's structure could be strengthened, inconveniencing many riders (including me a few times).
I realize Detroit doesn't have the infrastructure that New York City does, but deferring needed maintenance for many years will cause problems later on no matter where it is.
