What if Ayrton Senna had survived his Imola 1994 accident? What if Gilles Villeneuve hadn't died at Zolder in 1982? What if Stirling Moss hadn't crashed at Goodwood in 1962? What if Alberto Ascari had survived his 1955 testing-accident at Monza? This book explores those rivalries by assuming that drivers' injuries from crashes were not fatal, and pits the drivers up against their peers once more.
