In the near future we may see many more self-driving cars from many different manufacturers. If this is the case then we should think about reducing the number of roads and lanes devoted to cars. As robots drive cars, rather than humans so safety distances no longer need to exist, because every car is talking with every other car, as a swarm.
Traffic Swarms
As I listened to a podcast about drones one of the people said “they write about swarms of drones but these are not swarms, for it to be a swarm each drone should talk with every drone and they should work as a single entity. Given this context I look forward to when we live in a world where cars are programmed to be part of a swarm, rather than individual units. This is because if cars drive themselves, they can be much closer, at a higher speed, whilst still being safe. It means that rather than have two or three lanes of traffic you would have just one, per direction. Imagine a motorway where cars behave as train cars, rather than driven cars.
