*sigh* That looks disappointingly similar to my wife's car. I have no idea how the fuck she collects 3 days worth of water bottles, coffee cups, banana peels and pop tart wrappers when every place she buys those items has garbage cans NEAR THE CAR.
My wife had an Escape, and it looked just like this all the time. I would clean it out for her, and a couple days later, BAM...full again.
Bought her a 4runner a while back and told her if I found it like that, I would drive it myself, and she could have the Escape back. Needless to day, I have a Tacoma AND a 4runner now. The sad part is, when she gets home she literally walks by 2 trash cans.
