Here to, but not on new cars. If it is an old car, it is allowed. by old, i think the law came in in the 90's. I know the 70's Valiant Charger had one...
But we are lucky. how dangerous is the '57 Chevy, with its spear like points!
it's just the silly European-only regulation that make them illegal.
Well these can still be quite dangerous when a car hits a pedestrian
I am happy that the Mercedes which hit me did not had a fixed hard ornament (C126, if I remember well)
