Paint Markers are great for writing on your Cybertruck
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.)
Parts and repairs cost money. Then there are subscription fees. Not to mention all of the free data you give the fucker simply driving one that get transmitted to the company.
The fact that you think owning a Tesla you bought 10 years ago means actively supporting a Nazi, but telling people to vandalize that car somehow doesn't mean you're responsible for an increase in repairs is next-level delusion.
But thanks for the preemptive cop-out to avoid having to admit you were wrong.
Who do you think provides those parts and repairs? Teslas generally don't get repaired at 3rd party shops... You're advocating for creating business and generating revenue for Tesla
