Azrael The general theory behind push and pull on fast road driving is basically what you said. But you dont PUSH the steering wheel as it leads to unsmooth movements (what you want to avoid) so you pull the wheel with the hand the same direction as the corner. So left bend pull with left hand. right hand should only be holding the wheel not actually applying any pressure.
So, as you approach a sharp right bend. move your right hand round the wheel so you have enough distance to PULL the wheel and not push it round the corner, you should have your other hand pretty much opposite it. so that it still looks like 10 and 2 but they arent in the same place. if that makes sense?
If you push on corners you go round them like you're going round a 50p corner.
