> Mine has 25k miles and zero degradation yet.

Let me guess - Hyundai? They are notoriously lying about degradation.

Rivian I think it’s eating the extra buffer but that also means that the worse degradation that happens in first year is « free ». Then stats are a few percents per 100k miles…. There are articles about stats on long term degradation - it’s a non issue. Buy used if you can in USA - people perceive them as degraded so price is cheap but they don’t degrade fast
