Nitpicking but compasses are useless in a driving EV.

Why, the motor makes too much of a magnetic field? What if it corrected for the field it projects the motor to make at a given speed?

The display in pretty much all GPS units uses a compass to orient the little car/human thingie. I've never seen my phone map display be disoriented by accelerating in an EV.

Maybe they are using GPS bearing with gyro compensation?

Why is that?

Claims without explanation don't move the conversation forward much.

Oh, ye, the current gives strong magnetic fields.

YMMV but I've done IMU measurements in a EV and the compass course changed like 90 degrees from zero to full throttle. Was a low voltage 50V EV prototype though (higher currents).

To be fair I'm not too sure how sensitive compasses are in high voltage EVs.
