It wouldn't take a nuclear physicist to figure out The Stig has considerable F1 experience but holy sh*t, it turned out to be Schumacher, arguably one of the greatest of all time?!
That explains the otherworldly control skills the Stig possesses; he could make any beast, even the hopelessly impractical Golf W12, go around the test track while Jeremy couldn't do it once. [so he said]
But why would they expose who the stig really is? It was so much fun trying to guess who it might've been. Damn!
Wait! This may be a ploy to pull the wool over everyone's eyes about the Stig's real identity. Hmmm...
