Earlier this season, during the Ardennes Classics, I was chatting to a pro team staffer about how they use TV pictures in the team car - for example, he told me that there's always a bit of lag from the live action, which limits it a bit, but it can be helpful for things like trying to work out how knackered your rivals are.
"And of course, there's the invaluable commentary," I said. "I mean, you wouldn't want to be without the tactical observations of people like me."
