Driver safety is undoubtedly one of the main concerns for all automakers, but so is pedestrian safety. When accidents happen, airbags inside the car can save the passengers. But, if the car collides with a pedestrian, he/she may not be so lucky. Swedish automaker Volvo has decided to change that. Volvo has built the world’s first external airbag for pedestrian safety. The carmaker has already unveiled the new safety system at the Geneva Motor Show in Switzerland this week.
