My point is that even if the overall age distribution is constant, you'd need EVs to work their way through the same lifespan before it came out the same. What we need to know is not the overall distribution, but the age distribution per ICEs and EVs. (Otherwise you end up in a situation where the overall age curve is constant, but EVs are the majority of the young part of the graph, which makes them look good because they're all young and the ICEs look worse because they average even older.)
