But if Rosberg wins it this year (barring any unexpected tragedy in the next few months) it will be the first time a World Driver's Champion lived to see his son win the title. And I suppose the first time a WDC's son equals his father's number of titles as well, although both of those fall solidly into the realm of trivia.
I wonder how long it will be before a third-generation driver wins a title? Or even races in F1, for that matter. It doesn't look like it will be Damon's son at this point, so at a minimum we'll have to wait probably twenty years or more to find out.
