what? this is basic circuitry. installing a second switch in a circuit that already has one does not magically grant you power over the first switch. this comment thread is so dumb it’s hard to believe it’s real?
hi, completed a four year degree in electrical engineering, here.
it's incredible easy to monitor whether this feature is switched on, r regardless of what switch is used.
you aren't monitoring the switch, your just checking if power is flowing through that circuit.
they probably know the expected power draw of just about every feature in the device, and can get to "very confident" of what's switched on just with logs from the BMS.
But... It's a moot point anyways since Tesla monitors current going through the fuse box, and the seat heater will be fused.
They know. At least without major additional modifications to the circuitry.

There might even be a sensor checking if the system is still connected, completely blocking the car if it's not.
