How do you spot an F1 driver on a plane? He's the passenger with the helmet…
Flying back home to Europe after the Mexican Grand Prix, Carlos Sainz posted a picture of himself on social media, snuggled in his seat, wearing his helmet.
"Helmet was booked for 71 laps," he wrote. "Need to use up the remaining 43. Positive weekend in Mexico anyways."
A breed apart they are these F1 folk.
