A self driving flying consumer vehicle that is fueled by any organic material (100% clean) would be the "biggest achievement of the century". Road/highway infrastructure would be a thing of the past. Billions (if not trillions) of dollars saved in new road construction and maintenance. Can divert federal/state/local funds to education, public health, and social programs. Then highways can be replaced by housing infrastructure and thus slowly driving down the cost of housing in markets across the country.
