If we give Schumacher the benefit of the doubt and assume that he didn't approach Rascasse with the intention of parking the car and we assume there was an initial innocent mistake (very strange entry line, for one, and the initial corrections and lockup), was it beyond an experienced F1 driver to get the car around the corner?
If Schumacher had been leading the race and made those initial mistakes, would he have got through the corner without stopping against the barrier? I'd put money on it that he could.
We know Schumacher's been known to make split second decisions of a dubious nature before, so I'm more inclined to believe that once he'd screwed the lap his instantaneous reaction was that a yellow flag would be good, rather than it being more premeditated. The only thing that points towards it being more 'planned' was the stupid line into Rascasse, which looking at the onboard footage approaching Rascasse, didn't seem to be through running wide, but rather through an early turn in. Prior to turning in there were only small steering inputs, and although he wasn't hugging the barrier on the left, he was still mostly on the 'rubbered' racing line.
The FIA stewards had access to far more data than we do and have stated the entry speed was no higher than normal and that he braked considerably harder than normal. They also interviewed Schumacher and team members (lets hope Schumacher managed to act less guilty than in the PC). I really doubt the FIA would choose the verdict for popularity (it's not something they've done before), and given the time they took to reach their conclusion probably discussed every possible scenario.
For me, of the three basic scenarios:
1) mistake(s)
2) initial mistake and then instantaneous reaction to park and bring out yellows
3) Not a mistake and fully planned earlier in the lap
It's a shame there wasn't evidence to show 1) because it's become another black mark (or as Schumacher calls them, black dots on his white Jacket) on an amazing career record. I really don't want to believe it was 3) and my gut reaction (based on our limited evidence, the FIA’s verdict, and dare I say it, past misdemeanors) is that it was a case of 2).
But it's just my opinion and the one that counted was that of the FIA. In the end Schumacher produced yet another fantastic drive in the race, with not a single mistake at Rascasse
