> MPG drops with the life of a vehicle, and it's not actually clear that behavior is much different from battery range loss... That's incorrect. Not sure where you heard that. MPG drops, sure, but it's so little it's hardly worth measuring. My intra-city full-tank range on a previous petrol car I owned went from (when almost new) ~800km to (350000km later) ~780km. No repairs other than services. The other cars I've owned show no measurable difference in range as wear increased.
