>If you're an American and don't know what it's like to have your country and culture reduced to about three wildly inaccurate stereotypes...

...you can watch Borat, which is far less about Kazakhstan than it is about the US.

I don't think Borat works as well for this. Borat was made for an international audience, including many Americans, and involved Sasha Baron Cohen meeting Americans in person to wind them up, so there had to be an element of accuracy in his satire. Top Gear, on the other hand, was made primarily for a British audience, so the jokes in that episode are very much lazy stereotypes that the British have about Americans without having to be too rooted in reality. I imagine that the production crew spent some time looking for a filling station where they could provoke the 'throwing rocks' incident, for example.
