An electric vehicle is a good thing. Just, it is unable to use a compass inside the cockpit, due to the engine magnets.

I'm guessing that motors can be magnetically isolated like some speakers.

The Faraday cage easily isolates field variations. But there are only extremely expensive and extremely cooled super-insulators that can effectively attenuate a magnetic field.

Knowing the compass receives a magnetic field (but not the variation of magnetic field), the magnets of the powerful engine (near 0.1 megawatts in a volume of a gallon !) break the Earth magnetic field.

I don't need a compass in my car. I always use a sextant.

Note, kiffi I do not need anything inside the car. The weather here is often covered (grey sky, rain, etc...).

So if I want to know where is north in the places where I go, I use a compass. I just have observed the tool inside the car were fully crazy :

On the driver place, the north is to the left.
And on the passenger place, the north is to the back.

I deduce we can create an application which knows if we are, or not, in an electric car. The gyro indicates if we are in a car. And the compass indicates a fixed magnetic field line if we are in an electric car.
