While you can interact with anything other than getting people to talk there is nothing meaningful to do, you are not going to starve or dehydrate. It is somewhat humorous being able to fiddle with some of the controls for driving, and you can glean understandings about the characters from some of the objects. Even driving you cannot turn on lights and do not need to overtake or even change lane. It is relaxing however and encourages choices of narrative to build interpersonal relationships with the characters.
