But it is simply not true to say that “literally all other cars” other than Teslas

You’re right. It’s news to me that there are other car manufacturers out there implementing this horrifically moronic concept. Sadge.

At least it isn’t mainstream. If there are other cars out there with this plague then at least it’s few and far between. I’ve never seen it in any car I’ve ever been in.

I’d like to think it hasn’t become mainstream due to most people agreeing with how stupid of a concept it is. One can only hope.
