Compass's don't work in relation to vertical direction.. but in relation to your statement, anybody who does not know which direction is on their left or right given a direction they are pointed, should not be driving.
If I'm going west, I should always know that right is north, and left is south, and it should be common sense for any given direction. This is something we all should have learned in 5th, 6th grade? Earlier? Maybe they should add basic directional coherence to the mandatory driving test before you get your license?
The compass works like any other globe compass, and is what most people are used to. It's not buggy, it's functioning as designed, which is "correctly"
