That's a terrible and misleading paraphrase of the above post, whose main point was contrasting the extreme risks inherent to auto repair to the mundane risks of computer repair. Which makes some specific arguments brought up against right to repair like battery replacement being too dangerous for independents/end users seem unconvincing. Perticularly because vehicles themselves have dangerous batteries.
Here's an allegation of that argument being brought up by Apple.
However IMO this is a case of "A is much more complex and dangerous than B, so there is no reason to have B driven by more secretive and restrictive standards than those applied to A"
