The lesson from this new video by Stuart Edge and Chad Future? Don’t leave your car running and expect a complete stranger to stop someone else from driving off with it. <br /><br />For the prank, the two would stop their expensive car by a store, and ask random bystanders to keep an eye on it. Then, with the hidden cameras rolling, one of their friends would calmly get in and drive away. <br /><br />Sadly, very few of the people on guard even seemed to notice or care, though many simply assumed it was a friend driving off. <br /><br />For the icing on the prank, the original driver would return shocked that his car was apparently stolen right under the bystanders’ noses. <br /><br />http://www.youtube.com/watch?feature=player_embedded&v=pCOtbaBmq3I
