Blaming something on the user is very very common everywhere. For example with car accidents (drunk drivers), guns (mentally ill people), etc.
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.
