> The quest won't work in a car as it uses gyros.

I did try the quest 2 on a plane and it worked well, apart from when the plane was turning or in turbulence. I suppose the visual tracking makes an assumption that the world is static, which is usually true but breaks down when the plane is bouncing up and down.

It did work a little bit better in a plane when I tried it however I couldn't get past the unlock screen because I hadn't quite paired it correctly and I didn't have internet and the quest needed to do something with the internet. This actually brings up one of the biggest issues I have with some of these systems is they are too tied to the internet for remote work

If they ever wanted to fix that, it seems like it'd be pretty easy to do by having a wireless IMU and gryo you could attach to the vehicle itself, then subtract that from whatever the headset feels.

Not an assumption: movement is relative. Quite fun to think about it (Einstein's elevator mental experiment)

But here the movement is relative to two things. You're aware of your motion relative to the plane, and the headset is aware of its motion relative to earth's gravitational field. Einstein's elevator experiment only works when you're traveling on a (reversed) path that matches one that would be caused by gravitational force.

The other thing to think about is a lot of these systems use kalman filters and sensor fusion, so stuff like a compass will cause drift. They jsut didn't design the software to think about movement. It could be conmpensated for.
