Maybe they could run this thing on HHO gas
We've heard for ages that future transportation will be flying cars. Does anyone really think the future will be like the Jetsons, with us trying to jam our "car" into the crowded "freeway" airspace? When there's no roads required, people will tend to want to go directly from A to B. What a mess that would be to regulate!
Oh, and you think you get lost now when you have directions like, "Get on I-AA, drive 20 miles, get off at Exit X, turn left, go east 2 miles, and turn left again." Flying directions would be, "Fly heading north 14.7 degrees west 18.2 miles." Try that in the fog or a snowstorm!
