Not sure I buy into the blackout/electric shock theory given that Alonso was not only applying pressure to the brake pedal, but was also downshifting at the time.
And of course, Alonso can’t make a statement about what happened because he suffered amnesia and can’t recall the crash. The danger of repeated concussion injury cannot be overstated. Can’t say that I blame him for taking doctor’s advice and sitting out the first GP.
I do find it strange however that McLaren haven’t released any telemetry data, I can only assume that it’s been passed on to the FIA for their investigation. Given that both Button and Magnussen drove the car the following days without reservation, I strongly doubt whether there’s anything sinister going on.
