Re: What about the free market?
First, I find those Ts & Cs appalling and would never buy a Cybertruck and by extension now, will never buy a Tesla - there's better electric cars on the market anyway.
Now that's out of the way, not being a lawyer myself, I don't see anything illegal about that. You buy a vehicle and the sales contract includes those terms, you accept them. They don't violate any constitutional rights or anything like that. Buying a vehicle is a free market act, and there are other alternatives. I would never agree to terms that I cannot resale and if I do I have to give money back to the seller, that's just lame, thus I will use the free market to make another choice.
This announcement from Tesla just affirms my decisions when I go electric, it's not going to be a Tesla.
