Has anyone driven an S-Class? It has almost every one on that list. What's it got in there that the others don't?
The 2014 model has even more of these options, see: http://www.slashgear.com/2014-mercedes-s-class-revealed-and-...
Otherwise I'm guessing it's probably all just part of their standard tool chain and someone said "give me a list of all open source software you used while developing the software for the S-class".
