I appreciated in particular the fact that they really did it like the ad is showing it, by parking a lot of cars in the desert and turning their lights on and off, as opposed, for example, to the recent ad by Samsung with the sheep in the hills (http://www.youtube.com/watch?v=5iCXvJ-jJzI) that clearly had at least some parts done artificially.

Nowadays, the whole point of that kind of things is to do it for real. Doing it through CGI is just easier and defeats the purpose. It actually reminds me of the Bravia ad from 4-5 years ago (http://www.youtube.com/watch?v=-zOrV-5vh1A&fmt=22) where Sony had tens of thousands of colored balls bouncing in a San Francisco street.

The collaboration with Vimeo with the Flash overlay is also a nice touch.
