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?
I dunno but presumably
government the community did not have their eye on the ball when despite it taking ten years to complete the ring-road, they completely failed to widen the few miles of interstate that joined it up to the large and rapidly growing business area nearby.
