MEXICO CITY -- Haas boss Guenther Steiner has explained why the team told Romain Grosjean to "shut up" as he voiced his concerns about whether his car would make it to the end of the U.S. Grand Prix.
Various transcripts have emerged since the race in Austin of a frantic Grosjean voicing concern about the state of his front-left tyre. Though not broadcast on the official world feed of the race, the audio was made available on F1's official app to members with a subscription.
The messages do not carry an individual timestamp from the race and have been thrown together into one 46-second audio file, which gives a misleading impression the Frenchman's complaints all happened at the same time.
