Prost thinks there is more to it. “Historically, it’s very difficult to say, 'this is similar to how it was then with me and Ayrton’. You cannot compare personalities, the human side.” Drawing parallels is also difficult given the environment in which the pair do battle. “Today, you cannot do things you did in the past,” Prost points out. “What he did in Japan [in 1990], when he said he deliberately crashed into me, maybe he would be penalised today.” This, more so than the glance of Rosberg’s front wing against Hamilton’s rear tyre, was the most explosive element of the Spa-Francorchamps ruckus.
