Imagine thinking that "high-speed self-driving cars, electric airplanes, and maybe even Hyperloops" are viable solutions for transit problems of today when none of them exist in any real viable form and have major obstacles to overcome in order to exist. Reminds me of the craze with pneumatic transport in the past. It too was the way of the future and NYC even had a model pneumatic subway line https://en.wikipedia.org/wiki/Beach_Pneumatic_Transit https://en.wikipedia.org/wiki/Beach_Pneumatic_Transit. Lost out to the normal train by a long way.
