Have you ever found a mouse in your car?

Today I was going back to my car after taking my daily walk in the park. When I got in, before I even started the engine, I could tell something was scurrying along the floor. Sure enough, there he was, frantically trying to get away from me. So I got out and opened all the doors and out he jumped out and went along his way. I got to thinking. This should be a more common occurance than you think because mice are always seeking shelter and cars should be easy enough for something that small to get into.
