text: Self driving cars are computers they can communicate with each other, they are programmed to read the road and communicate where they are and how fast they are going to the cars around them so all the appropriate changes to speed can be made in a fashion that humans cant due because we can communicate to each other from 2 miles away, and since humans no longer need to communicate at all all road signs that are required not to ensure that traffic knows where its going will be a thing of the past. with this out of the way there is no more need for upkeep of these signs and communication devices they can be taken down and recycled for something of more use or recycled for money saving tax dollars while also making the envioment better by reducing all the cluter along the road ways. it will also shorten how much time is taken to reach a destination which might just extend out time on earth.
