There are a bunch of Teslas in my neighborhood, some belonging to people I know well. None of the owners has shown any signs of embarrassment about owning a Tesla.
Once they have the BlueTooth chip on their brain tissue we can more accurately monitor these things. Until then, you'll need to wait for them to speak out. I also know Tesla drivers, and a solid half of them are speaking out against Elon and how they find it embarrassing.
