The other thing to know about this is that it’s normally a good partnership. The driver has to trust the copilot to know what’s coming up and to tell them in time. The co-driver has to trust the driver to drive fast without crashing. It takes a while to develop a partnership like that, and when it’s working well it’s amazing. The driver is basically driving what he can see plus what he’s told is ahead. If the co-driver says the road opens ahead, the driver will accelerate into a turn even if he can’t yet see that it’s straightening out trusting that by the time he runs out of road the curve will be ending.

The Samir commentary sounds like two drivers paired for the first time, with the co-driver being the one who owns the car. Compare that to a team that knows what it’s doing.
