I do NOT know about the circumstances or the rationale for the road in your non-rural tennessee location, except for your proclamation (one citizen's assessment) that it was NOT necessary b/c they could have substituted flying cars in that location.
It is certainly
a solution but is it the
best solution? Are not people running around waving their hands in the air about the amount of CO2 motor vehicles are emitting? What about traffic fatalities? Trees plants and animals killed and destroyed by increased paving?
Who gives a flying fuck (there I go again, with my recent favorite expression in this thread)?
These are all factors that the non-rural tennessee public could have taken into account when they were deciding about the best solution in the circumstances of that particular community. Did you go to any of the meetings that involved the discussion of the road? You could have had your input regarding the better flying car solution?
