I agree that our future self will look at 2020 as a being a very old fashioned way of doing things. Our planet is not getting bigger while he multiply. So the resources must be well used and new ways of doing what we need must be found and applied. Transportation is a major source of pollution. One person or maximum 4 in a vehicle driving occupy far too much space and pollute. We will advance to means of assuring other ways of transportation which will make driving school and drivers obsolete.Not to mention the human error and the accidents which can be avoided if we change the way we do things. I enjoyed reading this, thanks for sharing!
