Steering Wheel

Our buses have adjustable steering wheels. Very modern. Actually we have had adjustable steering wheels for lots of years. In the past you turned a knob and moved the wheel and tightened the knob. Nothing could go wrong. Unless the driver before you had a grip like a Black Hole then it was a bugger to move the knob. The buses we have now use a compressed air device which works fine, you press down on a button and a blast of air releases the catch. Except that now and then the catch doesn't release and the wheel just will not move. And when this happens you can bet the mortgage the driver you are taking over from has had the wheel as different from your position as you can get. Which is a pain in the butt, the back, the shoulders, the arms and the neck.
