YOU BITCHES FUCK SHIT
The mystery was the fun part, just why.... now we may never see the Stig again...
at least not the white one, maybe the black one might resurface.
I find it funny that it's a big deal now, since it's been fairly well-known for quite some time, just a wink-and-nod sort of thing.
Basically, after Hammond's crash before season 9, there was a report on the crash all the personnel who were on the track at the time, including The Stig, who was listed by his real name as the "Performance Driver" or something to that effect. Anyone that cared to read that document could have found out.
I hope they don't kill him off though, I like White Stig's outfit :<
