I can't help wondering if there is or should be some sort of law against corporations doing this. If they are trying to mislead you into not making use of a right which is legally yours, that feels a bit like fraud, or practising law without a licence.

I'm reluctant to suggest that the government should limit even corporate free speech so much that companies become afraid to put warnings on things, and corporate lawyers would probably just come up with even more convoluted ways of phrasing things to technically comply with the law (or maliciously comply with it to make people hate the law), but perhaps some well-funded consumer body should be able to name and shame companies that do this.

The FTC in the US has gone after companies that literally tell their customers that something invalidates their warranty, when under law, it wouldn't.

But I feel like "you are not permitted" is an entirely different thing. It is so vague that it doesn't really have a clear meaning, and it leaves the reader to fill in the blanks.

Splitting hairs here, but Mercedes would argue that it is meant to signal to leasing/rental cars that the user is not allowed to open (based on the rental agreement) so in those cases at least, it is not complete missleading.
