I think Fernando is a stoic, and he behaves as such when he's done his best and things aren't working out. If after several intense, risky attempts to get things out of nowhere... nothing comes out ... well, then, that's it: a beach lounger for sunbathing, messing with the TV cameras... it's the anger of a bored genius. In fact, he's behaving very well now; he cares about this going well above all else.
I suppose he's confident because now he has a good team behind him. They need to be given time because, although they're tremendous professionals and it's not impossible that the car could suddenly change for the better... just in case, it's better to give them some time.
By the way, I'd like them to take a good look at the front suspension geometry. The car's bottom end and aerodynamics are very important. But ever since McL worked the miracle last season and that little thing was changed (apart from other things, yes, this is where I get confused), since then... Hmm...
From what I've seen, Pirelli plans to introduce new compounds at Spa. Apparently, they're interested in a new medium. I'm scared of them. If it weren't for this whole thing, I think Spa would be a good track to observe Drugovich and start getting to know him.
P.S.: Thanks so much for the graphics, Diffuser.
