Partially so. A compass only gives you *some* of the direction. Particularly, the compass won't notice if the device spins around the north-south axis. Do it slowly, and the accelerometers may be too limited to notice. Of course, such a movement doesn't normally happen in a car. But you do want to notice if this happens to your plane . . .
