Google has answered a question that was a worry; how will they make their planned driverless cars safe to be around other vehicles and pedestrians? The answer it seems is airbags. Airbags like the ones we’re all familiar with but on the outside of the vehicle! The US Patent and Trademark Office has granted protection for Google’s design with airbags concealed inside bumpers. Still sound dangerous? Fear not, the airbag will be made from material a little like memory foam used in mattresses and pillows. So being hit by a Google car will be like being in a pillow fight? I guess we’ll have to wait and see.
