The above poster was talking about the entire car not just the motor. Sure, the motor is far simpler than an ICE. But there's still a cooling system, with pumps and hoses and heat exchangers. Those are all parts. There's still seats, with sensors and motors and mounting rails. There are steering assemblies, with linkages and actuators for power steering. There's the whole infotainment system, which contains just as many parts if not more as an iPhone would have. So when comparing the idea of a car having an order of magnitude more parts and complicated supply chains its still true even with an electric car.
