Teaching the kid to drive, we've talked about manual and automatic transmissions (we only have automatic) and why it's needed with gas engines. I don't think he really gets it (or cares). When I made my EV, almost 30yrs ago, I'd left the manual transmission in, not knowing the range of operation the big DC motor and not needing reverse electrical relays. City driving I used 2nd gear all of the time.
