I forgot about Japan 2000, with Schumacher and Hakkinen showing why they were the class of the field. .009s separated them in qualifying, and literally nothing in the race as they duked it out for what seemed like an eternity. And they were best friends. They were both a minute faster than everyone else, including their teammates. Everyone except Coulthard, Barrichello and Button were lapped.
The sheer fact that Hakkinen was able to take that title fight to the bitter end makes me think that, while he was extremely loved, he was also underrated. Top ten all-time material IMO. The Vettel of his time. A shame that he lost his motivation so quickly.
