Never seen this but who knows, they let him top speed a Bugatti Veyron. I dont think they will let him if he is really captain slow.

That would really be hilarious but I wouldn't be surprised if it was. Top Gear always comes up with these kinds of surprises.

The guy at the end of the 2nd vid is Shrick (or whatever), which is the same guy they show in the first video.

I've suspected the Stig to be James May in the past, but I've observed enough evidence to know that it's definitely not the case.

top gear esp jeremy is really good in making different speculation who's the stig.
