Imagine Daniil Kvyat would have went to have same accident instead of Grosjean as he cut him in worst racecraft fashion. Grosjean is so lucky today, not only that he escaped the fire, was not decapitated, not even a fracture, but also that he himself was there, and not Kvyat.
Things has kind of evened out for Grosjean. If after this accident he will still be unable to race properly, then he should quit.
Grosjean is surely star of the day, it is just thrilling and amazing how lucky he was and it is so outstanding that such accident even happened in modern F1. But he is worst driver of the day, no doubt about that.
