I am 97.2% sure he didn't do it on purpose. If you watch the in-car view, he takes his hands off the wheel when he hits the wall like he is supposed to, the wheel jerks around as it bounces of the wall, and he catches it immediately after, but the wheel is upside down because the front wheels have turned due to hitting the wall... then suspension broken, he's just a passenger with a split second to avert disaster.... maybe he should have stepped on the brakes sooner or something, but he just took an impact, is likely a bit disoriented from spinning and hitting the wall, and only has a split second to realize that his car is turning into the track, which he doesn't know it's gonna do... And I really doubt he decided, yeah lets maybe throw my life away for the championship by getting t-boned by a f1 car. the risks are too great at those speeds for anyone to think that is a good idea, unless they are monumentally stupid.
