OK, so we know this is a bit silly, but to give you an idea of how we envision to world in 200 years, please watch this video

It's nicely futuristic without being overly science-fiction (and no, not everyone will wear transition lenses).

As for transportation, most of today's transport is still around, but with some improvements. Yes, there are flying cars, however they must still obey traffic laws and fly in designated paths, just like how you would keep your car on a road.

There are subterranean train systems that connect cities and countries. These trains are extremely fast: in the future of Code Wars it would be possible to take an underground train from Baltimore, Maryland, to Boston, Massachusetts, in 15 minutes.

Airplanes are also still around, but have been majorly upgraded and refined. Flights are perfectly smooth and amazingly fast: it takes only 30 minutes to get from New York City to London.
