He shouldn't have to tell the start marshal not to that. He should know not to.. It's dangerous !! He didn't do it earlier, after all. But Oxford were on a 5-1 then. And if the ref did tell him to do it if it happened again (Heat 15), then the ref looks incompetent, and should be accountable. Both should know better. I wonder what would of happened if the marshal let it the tape slip, and it caught a rider on the was past. If i was Oxford I would let it go.
