Tesla batteries are currently
Tesla batteries are currently the King which other companies strive to compete with. They definitely don't have rapid degradation lol. There are batteries with well over 500,000 miles and their new 4680 cells are going to push them even further ahead of the pack. Fires are such a tiny number they wouldn't even register percentage wise when compared to the number of Tesla's on the road. GM on the other hand has a legitimate battery issue on their hands with the Bolt which I'm sure they will fix.
