I can see a vehicle like this having a place in addressing our future transportation needs. I think it would be a niche product for quite sometime before it would ever be a mainstream choice to own for most.
Renting a ride in something like this would be great even now for getting places a night’s drive away. In the future, when almost all cars are automated, much more efficient use of our roads and highways will negate any negative adding a car based alternative for some air travel might create.
Intelligent use of public transit will be a key element for our transportation needs as well. Technology like this isn’t a threat to those plans. In fact, taking a car like this from City to City, then moving about your destination via an improved public transit network, may be ideal for many future business travelers.
