The translation of the radio message at 19:28 is interesting...
"Yes otherwise we will swap next lap."
becomes in French:
"Max et toi allez échanger vos position"
I'm not a fluent French speaker but even I know that's a really bad translation - the team radio didn't explicitly say swapping positions with Max. It's very misleading.
What happens to RS16 at 5'55" at first curve (from Button onboard, or at 7'00" fros Grosjean's) to spark like this ?
No good turn goes unpunished.
