I drive a Jeep Wrangler, which is as secure as a tent. Basically, it IS a tent.
So the passenger's side floor is pretty much always full of Dunkin Donuts trash. I slide my laptop bag under it all, throw a few empty coffee cups on top, and noone's going to think there's anything interesting to steal.
Out-of-sight, out-of-mind works very well.
