What a load of......(Not very happy that you've been putting new tyres on the front, by the way.)
Absolutely agree on block changing.
Disagree on wheel shuffling - though I dread the discussion that's going to ensue. If the driver anticipates what steering movement is going to be required he/she can place the "pushing" hand appropriately and can negotiate any corner or roundabout without removing a hand from the wheel and without crossing arms (unless something really unexpected happens in which case I'd cross my arms, my eyes, my buttocks and anything else to avoid an accident but the last thing that I'd do would be to shuffle the wheel.) Apart from anything else I maintain that the action and sensitivity in pushing and pulling the wheel is so different that doing each alternately is a mistake, the pushing hand should lead and the pulling hand should assist if necessary.
If a driver anticipates what steering movement.......
So what your saying is that if something unexpected happens the driver is up **** creek with turd for a paddle?
