I have watched the incident. Exit of Hairpin and run up to Spoon. ( Turn 12). Contact occurs when LMP2 attemtps to pass GT car on the outside. lmp2 loses the rear end of his car and makes contact. Rules I will refer to the applicable rule. 4.6.Lapping Cars in a slower class always have to stick on the racing line and are not allowed to slow down or go off the racing line when being lapped by cars from a faster class. If a car receives a blue flag while being lapped by a car in the same class, the lapped car has to make way for the faster car as quickly as possible Bottom line is that the GT car is not required under the rules to do anything. He is expected to hold his line#. Blue flags don't apply except in your own class. Therefore the responsibilty is that of the LMP2 to find a safe way around ( a GT car that should be on a predictable racing line). Practicality On a more practical level the outside of a GT in a long corner is quite dangerous. GT cars have less grip and will often drift wide on corner exit or in long corners. It might have been safer to go under him than around him. IMO its an easy one. LMP causes contact while lapping a GT. # This is why it is pointless flashing lights repeatedly at people in slower classes as they aren't supposed to do anything different.
