Interesting article.

In my industry (unmanned air systems) advances in propulsion technologies (battery improvements, thin film cells, fuel cells, other gases, etc.) have increased endurance remarkably.

We call it SWaP: Space, weight and power, the three pillars of flight that drive limitless sub tasks. We have been able to take advantage not only of improvements in propulsion but also in the supporting technologies like avionics, GPS receiver weights, conformal antennas, auto pilots and materials...all leading to significant SWaP improvements with lower costs and improved mean time between failures.

I expect the same advancements in the auto industry.

They key, as always, is cost, maintenance, infrastructure and supportability. I can get in my stupidly inefficient Toyota truck and go anywhere at any time with no worries about any of the above with minimal attention on my part. I do not, selfishly, want to give that up.
