How do you know that it is safe to cross in front of a car in the street? Well if you are not at a crossing or traffic lights, you have to rely on what the driver says or does. Sometimes it is a wave or a nod. If it is a Robot Car, that can’t happen, unless there is a robot in the driving seat.

Swedish company Semcon which works on both digital and physical product development, has created a concept of a self-driving car which interacts with pedestrians and drivers by smiling.

In order to create the concept of the Smiling Car, the Semcon team had to investigate the way pedestrians reacted to autonomous vehicles in traffic. It is all controlled by Radar and computers, but after viewing the video how do you think it works?

Perhaps this is something we will get to used to. Remember to smile back.
