Someone genius thought that if we like using emoticons so much, why don't we use them on the road. It's the perfect place where you cant communicate directly, but still need to express emotions (although some times you better not). Now you can wink or teas the driver behind you just by pressing a button. The LED emoticon is powered by a remote control located in front of the car by the driver seat. It can display any one of five different messages - smiling face, frowning face, "Thanks", "Back Off" and "Idiot". Do you need more than that on the road?
