If there'd been any question whether the return of KERS energy-recovery and new adjustable rear wing would mean more passing in F1, McLaren's Jenson Button answered it this past weekend in Australia. Yes, Button pushed the button, and it worked.
Talk about making a mountain out of a molehill.
KOB had a poor exit onto the front straight, the Macca is a superior designed and more powerful car and he most likely would have been in that draft with or without KERS.
So Mike how many other instances did you find where the "push to not be passed" button worked as intended...
