Statement suggests that Alonso was conscious, braking, steering and downshifting to the point of impact (therefore no electric shock) and that it was a simple accident, car ran wide, partly due to gusty winds, outside wheels on astroturf, spins up and heads into the inside wall, which by some fluke knocked Alonso about a bit, causing a concussion. Seems plausible enough, Alonso is sitting smiling for pics from hospital, and I'm sure if there were more to it he wouldn't be wanting to cover it up
