Right; the whole conversation re: "what is drive by wire anyways?" is a massive red herring. That's really my bad. The operative question is just "what happens if the primary chip fails?" If the answer is "nothing bad, yet, but maybe something bad when we ship FSD" then Tesla's approach here seems reasonable (modulo not informing customers, which will probably catch them a fine in at least some of these jurisdictions, but in my book is more like a "mild breach of commercial contract" issue than a "fundamental consumer rights" issue). If the answer is "something bad" then this is a big deal and could be bad news for Tesla.
