The world already possess the necessary technology to make cars drive from one point to another without crashing into anything but they are not sending it out into the market yet because they need to be absolutely sure that it is safe.

Basically swarm technology mimics the super-organism nature of insect colonies and how each member of the colony can communicate about their surroundings to the others.
Cars with swarm technology will warn each other about road conditions, traffic hazards and even potential pedestrian crossings and weather conditions.
Self-communicating cars may conjure images of big brother but just like insect colonies, the Queen don’t have to know where the workers are to make sure that everything runs just right
