If this isn't one of the peak moments in car culture, we'll eat our official Boz Bros. motocross cap with a dollop of Hollandaise. The BBC's Top Gear aired its "Polar Challenge" in stunning 1080p high-definition TV this past evening. We have no idea where one might procure a viewable of the entire program, but teaser clips are available online. It looks absolutely brilliant. Now if only we could get a video card that could handle the full version on our Briggs and Stratton laptop. Thanks to Trevor for the tip. [Top Gear]
