Reply to comment by pulsebait in eli5 why is the age of a car determined by it's mileage by pulsebait

In practice it seems good enough for most cars. If you have an extremely special use case (eg. a police car idling by the side of the road all day), your mechanic will take that into account.

Planes, by the way, use hours, takeoffs/landings (the number of those is assumed to be the same) and, for big ones, pressurization cycles.
