Met him as well, I must say I had a different experience. It was however when he was still at Williams.
Went to Budapest for the F1 weekend and saw him walking down the Main Street while drinking something with a buddy. Got up and approached him. He was super friendly and we had a talk for about 10 minutes after which his bodyguard took a picture of us together. I wished him all the best and a competitive car for the future.
I must say he was a champ on a human level that night. Maybe I caught him on a good day, maybe you caught him on a bad day, maybe he still hasn’t gotten over his rivalry with HAM and the stress that came with it.
There are plenty of valid reasons to dislike rosberg, but a lot of drivers have admitted to that. It's not that big a deal, in the heat of the cockpit it evaporates if it isn't absorbed by the race suit.
It seems only he gets mad about this. I mean in 2023, who the hell is Britney? The checkout girl at the 12 items or less lane in a small grocery store? Just let it go dude.
It must be something that really annoyed him. He might not be as bothered about anything else but it was definitely a mistake to have shared that publicly as people are now going to call him exactly that.
