I think you missed the point of the OP. The question was not should a cruiser avoid a race. He should if he can. The issue was what should happen when racers and cruisers happen to meet.or do you give him an extra wide berth to be safe?
So why not give some racers a bit of breathing room?
I'll turn your question a round - shouldn't the racer give the cruiser a lititle extra berth especially when it's his legal and moral responsibility to do so?
