what has mercedes done?

well as you may or may not know there is a new sprinter coming out.... i thought yay i like sprinters, but then i saw the spoiler picture. lets just say i no longer like modern mercedes
this is the citroen c4 cactus of Germany. what the fluff are those plastic lumps all over it

 

You know that's a spy photo of a prototype, right?

 

All car manufacturers put these plastic panels when testing prototypes in public.

 

of couse i know that

 

Then why would you say it has lumps over it when this is a standard prototype camouflage manufacturers use all the time
