What I don't like is when you repeat things which didn't work in the first place. That frustrates me because, if it doesn't work, then it doesn't work. If I'm told that something looks much, much better in the wind tunnel, that's different. But I've driven for some teams where their guys just go away and rub a bit off here and there and want you to try again. Formula 1 can be funny like that.
People get bees in their bonnets.
Yet they just seem to keep pushing it forward. That frustrates me, because it's unnecessary and wastes time when you should be looking at other things. I'd rather go testing and do, say, three days, but three days where it's all very methodically done. Where you do something, stop, talk about it, go on to the next step, talk about that, and so on. It sounds simple.
