   You do know helicopters spend a fair amount of time not traveling, don't   
   you, but that has nothing to do with flying cars.   
      
   The cost of the engine is a tiny fraction of the cost of developing,   
   certifying, manufacturing and marketing a flying car, or a flying   
   anything for that matter.
