FWIW, that sort of ultimate judgment (simple/complex) is nothing more than a personal point of view. I have consideralbe expertise in machine design and control, as well as in the cost and difficulty (or lack thereof) of making parts. My "simple / complex" gauge is different from that of other people.
Funny, I was just telling my wife, it’s relative. For GM, Ford, Tesla, not all that complex.
Still no reason for a VP to immediately contradict the POTUS like that.
