I don't think he means to be rude during races. They knew what he was like and AFAIK what we heard last season is not uncommon in any race. Out of car he seem jovial and relaxed, not rude in any way.. I've had bosses that straight up shout at my ear and when the clock stops and work is over, it's like they are different humanbeings. And we are talking about the same kind of high stress high risk job (rigger, climbs a lot to awfully high places that aren't even ready yet..) where there just isn't any margins: you miss, you're out, maybe for good. I didn't think of it as rude at any point, you respect the superman and deal with it on the ground.
