I've had this issue. It seemed to be caused by being in the crouch position when sitting in the driver's seat. Leave the seat, stand up, then get back in the seat and this goes away.
That's hilarious ...........It kinda reminds me of a movie that I use to watch when I was a kid, the movie was called Harry and the hendersons a 1987 movie, when a family took home big foot and they had to cut a hole in the roof of their car so big foot can stick his head out. I don't know if you Europeans had it over there. But, this kinda reminds me of that. Dang those childhood memories.
