Keep in mind that battery degradation differs depending on the cell chemistry, construction details etc. For example, data shows that battery degradation on older Tesla 3s was highest for the first 50K miles, then tended to level out. But current generation Tesla Model S and X have much less cobalt in the battery, and anecdotal evidence from many of us with cars around 100K miles shows that the battery degradation continues at about the same rate, without any obvious leveling out.
