It may very well be kind of neurotic or anti-social to spend all my breaks in my car. But I like the parking lot; this is my view. And I get the best spot in the shade under the big tree because I get in so early. (Yes, I'm Sheldon.)
I like sitting in my car and eating my lunch, or calling Greg, or calling Mom, or going on Twitter or playing a game on my phone. It's way more relaxing to me than having to make small talk about congress or work or some popular tv show with a co-worker/stranger in the break room.
