No wait, there is something stoopider. How about announcing your child's name and hobby on the back of your vehicle? Pedophiles just loooooove that. So easy to approach your dumb child and ask about their activity of choice.
If I have an option to avoid a collision with either an unmarked car or the stoopid decal car, you aren't gonna like my choice. Now, if you have a NASCAR sticker, it is gonna be a tougher choice. Make sure those air bags are activated, idiots.
