Me too (live in a place where cars go unlocked), but last night I watched a burglar open my passenger door, sit in the seat and look around. I never put valuables in that car, so I wasn't concerned if only for the awareness that my neighborhood is not as safe as I once thought. I shouted at him from my second-story window and he took off like a bat out of hell. The cops came and I now lock the doors on my beater every day.
