Steady on...
F1 (alone) - 2 world championships, 33 pole positions and 25 race wins (from 72 races), won 100% of available points in two seasons, record percentage of laps led in a season, and still holds the record for races where he led every lap, got pole, fastest lap and win.
Add to that he won the Indy 500 , British Touring Car Championship, French F2 championship and the Tasman Series three times.
He died at 32 and could have won more - but I reckon that he stands well enough on his own. No where near as impressive as Andy Murray? I'd argue that point with you.
