It is nice that you are
It is nice that you are highlighting this point John. Having had three Chevy Volts, and now a Cadillac ELR (all plug in hybrids) that is one point that quickly because apparent. Most of the car's braking is done with regeneration. Meaning that the actual brake pads are rarely used, and the brake rotors look brand new even after years of driving. On a similar point for plug-in hybrids most of the driving is using the electric motor. So a car with 100,000 miles on it may only have 15-50K miles on the gas engine/generator. This is one big reason why legacy auto dealerships try to NOT sell EVs. And why Elon Musk did not want to have a dealership model for selling Teslas. Because dealerships make more money on maintenance work than off of the profits for the sale of new cars.
