Most drivers have desired at one time or another to send messages to other drivers with more content than they can manage with hand gestures. And various solutions have been tried. It's probably good that no solution has been overwhelmingly successful, as incidents of road rage could catapult. The latest car-to-car communication solution, called Drivemocion, has an LED module that can show up to five different messages. The messages consist of emoticons such as a smiley face and a frowny face. It can also show text messages, such as "Thanks," "Back off," and "Idiot." The driver gets to pick the message using a wireless controller, a nice little bit of technology that makes the device easy to install.
