What happens when you take a group of Mario Kart fanatics, equip them with Razor Crazy Carts (which are insanely cool, by the way) and set them loose in a London shopping mall (uninvited)? If you answered loads of fun, you're right.

That's exactly what takes place in the clip above. The impromptu Mario Kart race played out at Westfield in London, much to the dismay of local security. If you haven't already checked out the clip or seen Crazy Carts in action, it's certainly worth a watch (even if it doesn't have a ton of virtual effects edited in).
