Nor do electric motors. Rings, cylinders, valve seats, there are plenty of ICE components that wear out or coke up long before anything on a brushless electric motor will. It makes more sense to compare batteries to tires and brakes; they're wear items. And their cost will keep dropping as their scale of manufacture increases exponentially until the economics start resembling tires too.
