Who is the is the stig?

May be...

My name is Ben Collins.

its michael schumacher. it was revealed a while ago..

Ayrton Senna.
I know Senna's supposed to be dead but that's exactly why the Stig never speaks.

He's not actually just one person, the stig is just a name for many different drivers which top gear invite on the show.

Who do you think the stig from top gear is??encryption pack
