Your race engineer is the only person you can talk to during a Formula 1 race. So you should have full trust in each other and be able to rely on each other.
Romain Grosjean thought was told to ‘shut up’ by his race engineer during the American Grand Prix.
Below this article you find the video but to make it clear this is what was told:
Grosjean: “Mate what was that? Seriously. I don’t know if I… I think we should retire the car. I think we should retire the car, no point in going to the end. I can see the whole [censored] left tyre. What are we doing, guys? Seriously.”
Engineer: “Shut up.”
Grosjean: “You’re not paying your life here. The tyre is completely gone. ”
Engineer: “OK dude so we’ll box to retire the car, retire the car. Box now. It’s the last lap anyway, man, but just bring it in easy.”
Grosjean: “I can go the chequered flag if you want, but…”
Engineer: “Yeah we’ll just take the chequer.”
