So just to make it clear you can't drive a car in say 7am Saturday morning and KEEP it within your 4/6 (not on the road/edge, within) campsite for the entirety of the event?
If this is true and given it's not how it has been previously or at the Mont etc, between 7-10am Saturday morning I'd expect an absolute clusterf@#. Is this widely publicised? Because if not a lot of people are going to rock up Saturday morning expecting to be able to drive their car in/drop off or leave it in there and are going to be throughly surprised when it's not the case. Combine a 2-3hr journey, the anticipation of the upcoming race and wanting to get setup etc and I sure wouldn't want to be those gate marshals....
