:Hill and Villeneuve:
This was the first full season of F1 I got to experience. I knew they were sort of friends at the time, but still it was odd because the 2nd place finisher loses the lead on the final lap but goes on to hug the eventual winner ?!? I mean... Get real
To this day I think that the gearbox issue was a made up story and Hill just wanted to help Jacques in the title race against Schumi 
Francois Cevert and Jackie Stewart:
I haven't heard much about their friendship but it is said that they were good mates and Cevert's untimely passing spurred Jackie even more in raising his voice about driver safety. It could be argued that his efforts were significant in saving others' lives.
Gerhard Berger and Ayrton Senna:
The pranks they pulled of on each other back in the day are still prominent among the fans of the sport. Years after his passing, Berger helped his nephew get into F1.
Now onto you !
