From the top of mind top drivers who retired from f1 at 36-37: Alesi, Coulthard, Irvine, Frentzen, Trulli, Fisichella. Villeneuve, Heidfeld and Häkkinen even earlier. Now Webber.
Although every retirement scenario was unique, the f1 market seems to have settled down around this age as best before date, kind of comparable to the often cited threshold of 40 for the career of Hollywood actresses. Why is this so? Fitness freaks like Trulli, Schumacher and Webber, for example, were/are probably still fitter at this age than their average f1 competitor.
