Most of those internal combustion engine maintenance parts simply do not exist one electric vehicles. You still need maintenance to fix / replace them, and that does not exist for most of those. The transmission on say a Tesla is a single speed and significantly simpler as a result.

As an example, the tesla model 3 warranty is 4 yr/50,000 mi basic, 8 yr/100,000 mi powertrain.

By comparison, the BMW M4 warranty is 4 yr/50,000 mi basic, 4 yr/50,000 mi powertrain.

Now the powertrain warranty being twice that of BMWs tells me they expect it to last at least that long. Perhaps I'm misreading something here?

The oldest teslas with the most miles are primarily taxis. I'm not sure I'd call a taxicab a "babied" vehicle.
