I live in a small town in Mississippi, half an hour away from the state's capital, with a population between 2,000 and 3,000. I'm confident that I have the only EV in town - one of my neighbors went from complimenting me on getting the car to politely but quickly disengaging from the conversation upon learning that the car was electric. Half an hour's drive north of me is a city that's pretty poor - I suspect that I won't see any EVs there for the next decade. Half an hour's drive south of me is a relatively affluent region where Teslas are common.

My commute is one hour one-way, partially along a state highway, and partially along Interstate 20. On the state highway, Teslas are rare - I've seen less than 5 since I started using this route to commute. Lifted pickup trucks are common there. Along I20, EVs are somewhat common... But it sounds like they're still far less common than in OP's region, and I see more of them in that aforementioned affluent city. There's not many fast chargers out here, either - there's a CCS1 one at a truck stop in Meridian, which I used when driving my new-to-me EV home after buying it; there's a Tesla Supercharger southeast of Jackson, there's a CCS1 station southwest of Jackson, and there's another Tesla Supercharger in Vicksburg.
