When driving your hands should be at 8 and 4 (not 10 and 2)

[DuaneBidoux]

11. They had shifted it to 3 & 9 for a while.

I had thought it was because from an anatomical perspective your arms had more force and speed moving vertically than horizontally. But the other poster's reasoning makes more sense especially now if it's been changed again to 4 & 8. In which case you would lose the advantage again gained in the vertical motion. Then the rationale about airbag sounds very reasonable.

I still think in the end most drivers need to make their own judgement about what is most comfortable for them. I am very comfortable for daily driving with right hand on 2 and left hand at the 7 to 8 range.

But on long trips of several hours my arms tend to drift downward with hand varying between 8 and 6 and right hand bwteen 4 and 6 changing positions slightly over time. This is simply because over time my arms start to get tired any higher than that and my thought is that it's not good to have tired and after a time possibly cramping arms.
