As far as rivalries go in Formula One, the competition between two drivers in the same team is far more intense than that between rival squads. Few have articulated that point quite as vividly as Fernando Alonso and Lewis Hamilton, the two star drivers at McLaren-Mercedes. One's a returning back-to-back world champion, and the other a wet-behind-the-ears rookie if there ever was one. But yesterday's race notwithstanding, the rookie's been acing the champion in classic style. As anyone who's been following this post-Schumacher season can tell you, it's been pretty intense.

Leave it to the Germans to lighten things up a bit. (Yeah, the Germans.) Mercedes, who, don't forget, through its Ilmor subsidiary, supplies the engines for Lewis' and Fernando's cars, put together this commercial. The video after the jump reminds us of two things: (a) a scene from that *ahem* "classic film" Days of Thunder, and (b) just how childish men can get... especially when it comes to fast cars.
