Hi Brian, I’m not sure where you are seeing this comment or what the context is (I couldn’t find it), but I can only think this may be something to do with having to have completed the IDS before acceptance to run in the Green run group at a DE event will be given. It may also have something to do with the number of cars we are allowed to put on the track in the Green run group.
I am not aware of any new rules regarding the Green Run Group or any ‘Green’ initiatives to run only bio-fuels or something. Maybe anybody with a Green car can drive for free with tires and fuel provided – I wish!
