Great stuff. Making me think how simpler electrocars are: no differentials, no transmission, no complex injection machinery.

  But: redundancy.

  I feel it's a bit unfair to those mechanical components to ignore how complicated power electronics are, for example. They are perhaps less inspectable for a layperson (what happens when you break it open to see the insides?) so we tend to treat them as more of a primitive black box building block, but treat the mechanical components as complicated assemblies of primitives.

  You need diff and transmission for EVs thought unless you have direct drive on two wheels.

    Yes, most current EVs (including Teslas) have single-speed transmissions at each motor driving two wheels via a diff. Some upcoming models, such as the Rivian R1T pick-up, put a discrete motor at each wheel, allowing each to be driven independently without need for a diff.
