It's typically his dad, Martin Lampkin or Ben Hemmingway doing the yelling. Listen to what they say and you'll find it's pretty useful information - "half tire right" etc... He does exactly that. Wish I could! Might not be such a bad thing having an ex-world champ or somebody on Ben's level yelling info at you. In any event, I suspect it helps Dougie or they wouldn't be doing it.
