(CNN) -- How do you go back to work when one of your colleagues has been seriously injured? That is the reality facing the field of Formula One drivers just days after French racer Jules Bianchi suffered a potentially devastating type of brain injury at the Japanese Grand Prix. "It's principally business as usual," John Watson, who raced in the sport's attritional era of the 1970s and 80s, told CNN. "But it will affect some more than others. "Today's generation of drivers have never seen what they had to deal with on Sunday. It will make them realize that they are no longer infallible."
