Ways of learning has grown and changed quite drastically over the generations. Previously it was only by spoken word that we had access to new information, but that was far too subjective and volatile. Then we created written word allowing us to store our knowledge on physical objects and share such information without having to be there. Books are still, to this today, the most popular way to access information. But something else is on the rise, video documentaries, arguably the best way to download information into ones brain, as it allows you to visualize in motion what books could only show in still pictures. Combine that with the power of the Internet and its quite a potent infrastructure for information.
This concept allows for even greater understanding of difficult to understand concepts. Beyond this we will likely have neural implants that allows for instant integration of knowledge on concepts and idea, but these of course would be up to ones choice, not forced.
I think cars need not exist. In the inception of their production I think a model should have been considered to allow for a universal public transit system, so anywhere you could get to by car would be accessible by some form of affordable, public transit which need not even be a bus. This would solve many problems.
The first being reduction in accidents as the driver, responsible for paying passengers, would be far less inclined to be drinking or driving like a maniac. They would (hopefully) be very timely and reliable so you would never be late for something. No need to pay outlandish car insurance costs just to visit granny, who lives in a rural area, for a weekend. Pollution would be taken down considerably, especially if hybrid/electric vehicles were used. Also, far less traffic congestion as every vehicle has a schedule and the roads would be built to cater to this system.
Cars are, practically ,only an expression of ones self to the public, in most cases, of course aside from the obvious need to get from point a to point b, but its unnecessary. Show who you are through your appearance while riding with strangers and be social again. Meet new people enjoy a new laugh, stop being so selfish. We needed this years ago and we need such a system even more now.
