In Sweden we remove the plastic cover from things we buy the minute it's ours, but here they keep it on til it falls off by it self.
I guess it's to protect it for as long as possible, but also to show that it's new.
Like this car. Cars are super expensive here so having one gives you a special status.
So there is always some left even if you try really hard to remove it. Not a very smart system, I must say.
