Should your car be cluttered with plastic bags, drink bottles and take-away wrappers, thieves might be under the impression that there are things hidden in your car – things a lot more valuable than a McDonald’s cheeseburger wrapper – and try to break in to your car.  It was listed earlier that valuables should be hidden well, though if your car is cluttered, this will hardly make a difference.  It acts as a lure, because curiosity will get the better of these thieves.  You can start by having a single plastic bag in your car in which you put all your clutter, so it looks cleaner, and you are safer.
