Not to mention bad for the environment ... unless they are hovering and not flying.

  On par, probably still better for the environment. Higher energy use would be troublesome but the ability to trash a bunch of parking lots, roadways, and highways paving over nature would probably be fairly significant.

    Wouldn't you still have the same problems with parking lots?

      Of course not! They would be attached to extremely long poles coming out of the ground, just like in the Jetsons.
