You're exactly right, and it's why I left some visible signs of the car. When processing, I tried a crop with just the scenery, and it had a very strange effect, at least with me. I started thinking that it was dangerous-looking, and I knew what the shot was! With the bits of car framing it, it's clearly, "Look at the nice view seen from the car."
Here's a cropped version: I'm interested if others get the same feeling. I have an idea about it.
Cheers,
Rick
