Often when we are in the middle of traffic, we need to communicate with those around us. For this reason there are lights, stickers (for example those who warn of the presence of a baby on board) and sign language. The idea is to propose an innovative device which, interfacing with their smartphone, may group them all. And do much more. A small monitor mounted on the rear of the machine, which allows you to transmit their moods (via emoticons), the sentences (via voice recognition of your smartphone), safety signs and even video preset. All with a simple touch, just like with the cruise control. You can so tell that you are slowing down, ask away, warn of a speed limit or just say hello. And why not, with a special nickname, allowing people to connect to other devices to chat in the middle of traffic.
