If you invite someone in your house, can they take your furniture or objects placed in furniture or items in general. Will they be able to use object? Ex: open a fridge or turn on the tv?

Alright, so Im not sure if this has been discussed previously in the forums because I could not find anything about it, but the question is: So, how will this game and its the whole role playing system ensure the well driving of others? Or in other words because Im not sure if I'm making any sense: How will this game or what system/law will be implemented so that people don't drive in to each other/ people/ and cars in the game? Im just wondering because in GTA its fairly easy to drive into another car/person etc, Im just wondering how well enforced it will be in identity and if it is even controllable.
