Always seemed a nice guy and comes across well on the Netflix F1 series.
My brother was involved in a Ferrari F1event in Monaco a few years ago, and he saw a bit of Vettel and Raikkonen. He said Vettel just spent the whole time being really friendly and polite to the staff there, including the ones who were at the very bottom of the ladder. I remember my brother describing him as looking like a normal bloke who was just really happy to be where he was, almost as though he was pinching himself all the time, thinking ‘this is mint! my life is great!’ while enjoying the whole experience.
Said Kimi was funny in a different way, and one evening he left the event and walked past security with a carrier bag with stuff like Pringles and chocolate, then got on his moped with his wife on the back and headed off to his yacht. Like a normal bloke having attended, ticked the corporate duty box, then snuck out to go and watch Netflix.
