Don't have a problem with this strategy at all.
It only affects Steel or Aluminium Bull bars on 2WD vehicles. You know the ones that go to town and are involved in wacking pedestrians or cyclists at about 100 to our 1 so "we" are never going to win that argument irregardless of our point of view.
"Smart" Bullbars on 2WD vehicles are OK and 4 X's are unaffected.
