I don't understand why there is so much focus on automobiles instead of just about everything else. In every other instance - airplanes, boats, long-haul trucking - the problem in significantly less complex to solve.
The only tangible reason I see for such disproportionate focus is some sense of false futurism; aka, driver-less cars have become the 'flying cars' of our times.
