What is your definition of part? Is a resistor on a PCB a part?

  I presume he means parts are likely to need replacement- i.e. that either move or are susceptible to degradation from heat. If you have to replace a resistor that's a freak occurrence. Yes electic cars do have heat and moving parts but it's more manageable. Fewer moving parts, no reciprocation like connecting rods and valves, no vibrations to speak of, and lower temperatures. If you look at the service manual for even quite modern cars, you'll see a vast number of parts that need to be "inspected, replace if necessary" at various mileage intervals. Sensors, hoses, filters etc. All due to combinations of reciprocating motion, heat cycles, and chemical breakdown. Also you have to bear in mind that we are probably close to the peak of ICE technology. What we have now, we have after decades of development. Electric cars are already competitive after a couple of decades of serious R&D.
