Michigan has more automotive manufacturing facilities than any other state, nearly 1,000 if you count all the suppliers and distribution hubs. And despite Stellantis now being French-owned and abandoning their headquarters, Ford and GM are still present with many dozens of facilities as well as their respective HQs.
Next closest is Ohio with only 600.
Detroit was the setting of RoboCop. Crime was pretty bad there in the 70s/80s. It’s much better now and the city is turning around.
However, worth noting that Detroit is in the lower peninsula of Michigan, and the blue “cars & crime” part here is the upper peninsula, which is basically super rural and low crime. I suspect this was done intentionally, lol.
