Note that she's driving up the coast on Highway 1 in this song (which puts the setting in California), and in the song "Torch" (which is right before this one on the album), she states that she misses their "Big Sur getaways". Highway 1 is the only road in and out of Big Sur. I think the implication here may be going to an old favorite place that she used to enjoy with a man she was very attached to, and making new memories of that place as somewhere she can enjoy on her own. Kind of way of establishing self-worth and independence and not being haunted by old memories. Or something.
