The tiny vehicles were fitted with stereoscopic cameras and speakers that played a series of sounds.
To demonstrate and promote their Eyesight collision avoidence system that makes cars ‘aware’ of their surroundings, sounding alerts whenever a driver gets too close to another object, Subaru equipped lots of mini cars with a pair of forward-facing stereoscopic cameras.
As Adverblog notes, the tiny vehicles were also fitted with speakers that emitted different sounds to show the technology in action and create unique music players, turning the cars into parts of an orchestra.
In the demonstration, a white cube is placed on the ground, causing all of the cars to come to a stop before they hit each other. Once removed, the mini Subarus then go on their way, driving off in different directions.
