Stefan Bellof. Sliding through the turns during the rainy Monaco made famous by Senna’s breakout performance. Despite the fact that if it ran the distance, Bellof here would have caught and passed Senna. He was that much faster. Things like this convince me. Senna wasn’t the greatest driver, he just worked harder and was a better student. He became a better champion driver. I seriously doubt Senna could have bested Bellof’s ‘83 Ring record of 6m 11s. I don’t think anyone else has.
