I was fighting for the lead with second place about two seconds behind me, and this guy assumed the racing line was his. I don't think I did anything wrong here, but he insists there are two racing lines in multi class and this is nothing like a single class race. I don't believe that is true at all and I think ultimately he is at fault for not overtaking safely. Nothing I did was unpredictable and he shouldn't be assuming that every single slower car in a race will yield the line to him.
