Is that a Star Wars joke?
Not at all. I was just joking w/ you.
My BIL once had a Triumph Spitfire. Before the restoration, while he drove the car, the wipers, radio, fan etc. and weird things came on mysteriously.
So, he rebuilt the Spitfire and replaced all the Lucas electrics/electronics with Bosch parts from a VW Jetta.
In the video, you mentioned that the driver's seat had moved mysteriously. So, my BIL story about the Lucas electrics/electronics came to mind.
Lucas electrics/electronics when working either they are on or off, but off most of the time.
The fact that you travelled 1600 miles w/o any hiccup proves the car's electrics/electronics are fine.
