At the end of my double lap, as I was resting, the lady across from me with a nice Subaru wagon, exclaimed she had been robbed of her cell phone, license and credit card.  Poor thing.  
Her car was directly across the parking lot from the water spigot, at the curved wall where we enjoy a sit down.  Fortunately, there was a police cruiser with two cyclist officers inside.  She walked down there to tell them the unfortunate incident.  All my own valuables were in the trunk.  How much do you think I could afford a robbery?  Therefore, I go through the trouble every time.

The local trail running community (where I've been hiding these last few years) has run into this a lot, every couple of months there tends to be a rash of vehicles being broken into (smashed windows) at the trailhead parking lots.  It's gotten so bad that some runners just carry their wallet, keys and phones - while leaving their windows down.

Maybe, but we haven't heard of any cars being stolen.  It also has the advantage of airing out the cars.
