As others have stated, this is irrelevant.
There are plenty of ways to get cars with gasoline engines to catch fire, and any attempts to sue every other manufacturer over the poor work of shade-tree mechanics is already something that has been dealt with for decades.
Moreover there are other manufacturers that are long as annoying to deal with as Tesla, particularly exotics -- they're just that, annoying -- that do things by the book, no worse than any certified manufacturer mechanic.
Hell, some independents are invaluable. My personal mechanic has had to have video calls with Porsche Classic (in Stuttgart) to tell them how Porsche badly did work (at great expense) on cars like the 959, that he then had to do right, because Porsche's official Classic restoration shop effed it up. He's functionally restoring lost knowledge at Porsche because the domain knowledge of those cars was lost -- and you'll find independent mechanics for Ferrari, Lamborghini, Aston Martin, McLaren, etc. that are also equally invaluable to keep classics running and dead reliable, and helping the manufacturers out by providing training, and ensuring there's a (very profitable) customer base with an interest for the old metal.
I buy and repair/flip lots of popular used commodity cars -- including hybrids -- as a hobby. Hybrids are increasingly popular for me because there's demand, and most mechanics haven't bothered with them yet, so it's a pretty easy $1800 - $2500 to turn around a Prius that needed a rebuilt battery from a reliable battery re-manufacturer that stands by 6-year warranties on their battery packs.
I've met Rich a few times at car shows. He's not a knucklehead, and Teslas aren't rocket surgery. Those battery packs are a different beast than the 40-50kg packs in a hybrid, but if you can remove a rear subframe with the engine, transaxle and rear suspension from a mid-or-rear engine sports car with a 6-to-12 cylinder, you're ready for a Tesla battery pack replacement.
