Battery degradation is also nice because unlike any comparable issue in an ICE it is never fast or a surprise. Your not going to go out to your car one morning and find it won’t start because one of the hundreds of consumable parts in the engine cracked apart overnight.

Coming as someone who has watched rebuilds of both ICE engines and EV batteries, i’d say that both require about the same amount of work, though modern engines are a bit tougher and more finicky.
