I don't know a ton of Tesla owners, but the ones I do know aren't "Tesla Bros" by any stretch. Half of them didn't even know who Elon was and once I explained the response was "oh that guy owns Tesla? I didn't know that".
I think the average population just isn't that in the loop sadly.
Easiest by far is just an older car with no wireless capabilities whatsoever.
I hear tell its possible to find the wireless antennas and physically remove them from certain models. If you're buying brand new, try to find a dealer that let's you not have any wireless capabilities. No idea if that's still possible these days...
As with any classicBMW@lemmy.world, its because the signals are broken, like most of the rest of the car.
