I remember discussing electronics with the Jag repairman working on my car. He recanted how Lucas couldn't just for instance, wire a headlamp by simply running a circuit from the power source to the headlamp with a switch in between.
He then pointed out the four (yes four!) rheostats imbedded in the circuitry!
I though only MB had the mantra "Why make it simple when you can make it complicated?"
