Pretty convenient when I unexpectedly find myself needing to use a parking garage and such. The scooter can take me out of the parking garage and into the building with no issue. And then I can keep it with me in the building until it's time to get back to the car.
It's also probably cheaper than a golf cart - mine was just about $3,600 brand new. Though used carts are probably cheaper still, and there are also much cheaper scooters.
I actually used to use only an electric scooter for transit, but then I got hit by a pickup truck who didn't check the bike lane before turning. So I did driver's ed, got my license and leased a BEV.
I do see people driving horse-drawn carriages, ATVs (probably illegally), snowmobiles (legally in some parts of MI during Winter or condition-dependent), and riding mowers (probably illegally) in and around towns, though. Very rarely, I see someone driving an e-bike; this rareness is mostly because they aren't allowed on the sidewalks here and there's no bike lane, so you need to drive and signal like a car, which is pretty awkward given how many e-bikes don't even come with real brake lights (though many falsely advertise red rear running lights as a brake light, which'd be illegal to drive unless you hand-signal whenever you brake).
Well, I guess you are not as well traveled in the Midwest as you think.
Sun City, Arizona, though these are golf communities/mega-master-planned communities. Coronado is a better example of a mixed vehicle environment with golf carts bopping around all the time on the same streets.
The golf cart isn't a replacement for a car, it's one you have on the side. I would argue that its partially because they're easier to park in a very touristy environment
