Cover art for Stolen Car lyrics by Bruce Springsteen

It makes sense to me that the "stolen car" is a metaphor for a woman that the protagonist is having an affair with. He's waiting to get caught so that he can end the lie. The "restlessness" he experienced was his desire for other woman and he hoped this would disappear as his relationship grew deeper, but it never did and now he's left driving that stolen car.

My Interpretation
