I was mad at that too but I have a feeling that they don’t build up stig or make him a meme like a British one for a reason.
Americans don’t like secrets and with pop journalism being a huge industry here the Stig wouldn’t last long as a secret ruining the meme in a season or two without the buildup that British one has.
Plus doesn’t help that the stig is the same height as Tanner and likes a bit of oversteer…
