Seriously I'm getting tired of this game which I truly believe will never come out, and I'm tired of such ridiculous questions as the one in this thread especially the first question. If you meant it as a joke I am not laughing.
I swear after following this game for 5 years, translating information, videos, interviews, and etc I have never seen such nonsense as your question about masturbation and picking up crumbs off the truck floor.
Sure truckers do a lot of things in real life, but you dont expect everything to be modeled do you? I'm pretty sure you dont get to see when the trucker goes to the bathroom, showers, and etc.
Plus this game is family oriented and if there will be romance as the developers said there will be, there wont be any hookers or any sex. Even asking such a question is so absurd its beyond my understanding why you asked it.
And about picking up crumbs off the truck floor, I mean come on!!!!
