They're very portable, so you can carry them around with you in case you come up with an idea of something to write on your Tesla while you're out and about. They stick to the surface quite well and don't wash off in the rain.
(Please try not to succumb to the temptation to write "F**k off Nazi Scum" or similar on somebody else's though like other people are suggesting. That might encourage people not to buy Teslas, which is a shame, because they're great American cars.)
Why are you saying that it is okay to support Nazis if it is not financially feasible to do otherwise?
It means we live in a car centric society and trading in their car wouldn’t allow them to have a reliable daily with which they can go to work
Or in other, more precise words:
"It is okay to support Nazis as long as you believe you require their products or services"
What a terrible thing to say.
Don't be a prick. People have to take care of themselves.
That said if your tesla is vandalized- but not damaged - then oh fucking well, get over it.
