A: To me, driving is a two-handed sport, and therefore the input from both hands/arms should be equal. There are some people who will tell you to push up on the steering wheel, and others will say to pull down on it. I think both are wrong – use both hands equally to rotate/move the steering wheel smoothly and accurately. Do I practice using just one hand? I haven’t. I’m not sure what the benefit would be, since practicing the “wrong” thing is only going to make you better at doing the “wrong” thing.

I suspect you’re talking about just driving a little while with one hand to see how it reacts, and I can understand why you might want to do that. I’ve never tried that (but will), but I think it would be better to just practice applying equal force with both hands/arms when rotating the steering wheel, and sensing the feedback through both hands.
