Az első poszt megírása közben akadtam erre a filmtörténeti következtetésre a wikipedián, a road movie címszó alatt:

Road movies traditionally end in one of four ways:

• having met with triumph at their ultimate destination, the protagonist(s) return home, wiser for their experiences.
• at the end of the journey, the protagonist(s) find a new home at their destination.
• the journey continues endlessly.
• having realised that, as a result of their journey, they can never go home, the protagonists either choose death or are killed.
