I really do hope that Alonso recovers full.
But from Vettel's description of the incident the whole thing is bizarre and almost as if Alonso had some sort of problem which led to him steering into the wall and subsequent impact.
Almost as if he had a physical problem within the cockpit, lost consciousness for a second or some other sort of neurological problem. Normally one would walk away from the incident and be ready to go a week later. But he genuinely seemed to struggle to find his balance and stay conscious after being helped out of the car and those are all troubling signs. Now with the latest news, it only confirms my suspicions that there may be more going on than meets the eye. The sport can ill afford to loose a major personality in this tough times.
