I do not think there is any question that battery degradation is real, but what is acceptable is what all EV owners have to decide. I'm at 7% after 2+ years. and that amount of degradation is fine with me. 5% of that came in the first year.
Yeah, unfortunately Tesla has deemed up to 30% degradation within 8 years as acceptable. I don’t think even the most loyal of Tesla fans would find that acceptable. They should have put that as 20%.
