No, that isn’t a photo taken at the Henry Ford museum yesterday. You are looking at a modern day Michigan State Police vehicle. That is a photo I downloaded from the internet. I didn’t get close enough to see a stationary one in person (fortunately!).
I thought I had remembered seeing a police car with a lone red “bubble gum machine” on top while on a previous trip but I couldn’t remember where it was. They have modernized it a bit, I suppose, as it isn’t a light source that revolves like they used to, but is a bright strobe light.
