Oh Honda, you spend a shit load of money and hours all for the most entertaining minute long commercials. Thank you for making me smile.
Honda sets out to turn a field in the desert into the worlds largest LED screen with the use of lots and lots of cars (Hondas, of course). In the spot, each of the cars' headlights act as pixels to perform an animated sequence. Brills!
Oh and look out for the Prius Insight at the end!
I would argue that Nissan has made the best car commercial ever.
