Audi is one of a number of companies letting the public determine the outcome of its 2013 Super Bowl commercial. It's sort of a crowd-sourced "choose your own adventure" exercise, also being used by the likes of Coca-Cola. Audi's ad features a young lad on prom night without a date. You can check out the first of three endings below.
The commercial should appeal to the nostalgic tendencies of the coveted 18-to-30-something male demographic that companies are constantly pining for. One might be inclined to call it Quentin Tarantino-esque, what with the virtuous underdog character rising up and fulfilling a sort of revenge fantasy. That's probably going too far. It's a decent ad, in any case.
