It's not a myth at all, and Tesla's "rating" is a lie. Look at data on Prius battery packs and what Toyota rates them for(100-150k). I understand I'm comparing a hybrid to an EV, but there is much more data and I actually trust Toyota.
Buying an EV with 100k miles and the original battery pack for 20k is a bad idea.
