For some reason, people seem to believe that EV's don't have cooling systems. I would invite you to remove some of the trim panels under the hood of a Tesla and you will find far more cooling lines than in an internal combustion engine. In your traditional car, you'll have cooling lines between the radiator, engine, and heater core. In an electric car, you will have cooling lines between the motor, radiator, battery, electric water pump, heater core, potentially the inverter and other power electronics, potentially a second drive motor on the other axle, etc. I'm not trying to discount the point of this post, but beside the fuel system (tank, pump, lines, injectors) and the actual combustion portion of the engine, many of the systems are very similar, if not the same, between EV and ICE. Parts shortage is always a challenge on older vehicles, especially when the aftermarket options are not of the same quality as the OEM parts.

I'd add one more significant system to your list — the transmission. The whole powertrain will more or less be vanishing.
