The Amish around where I live (Midwest) run a bunch of great little stores (which is most of the contact I have with them personally, but my partners mom has friends in their community who come to visit now and then.) The stores all take credit cards and have refrigerators for the cheeses/dairy, and many of them do use machinery for farm work. Some even use cell phones.
I haven’t noticed any jewelry (haven’t paid attention), but they really do seem to pick and choose which portions to adhere strongly to.
I’m in the same boat. So much that I just paid a bunch to replace the transmission of my 2012… I could probably have not done that and invested in something newer, but I don’t… want that…
I’ll stick with just getting more of this exact car when this one isn’t repairable anymore (it has telemetry, but it can’t be accessed without plugging in directly, which isn’t typically a huge concern I have) Or when they can be flashed, as you say. Like I’d love to have an EV because I rarely drive far, but I absolutely won’t buy a spymobile to get one.
