Well, as a company you can choose to do the right thing, or you can choose to weasel your way out of uncomfortable situations using lawyers and the fact that the law is always lagging behind technological development.
BTW this isn't even about any lawyers and EULAs, there's simply no legal way how a company like Tesla or Mercedes could take responsibility for a crash, so IMHO Tesla is at least nice enough to spell it out, unlike Mercedes.
This seems unlikely to be true, unless of course they weaseled themselves in this position.
