Elon Musk's quote comes to mind now whenever I read about flying cars: "A bunch of cars flying all over the place is not an anxiety reducing situation"
The mini Cooper, who's AC vents are optimized to freeze your knuckles while leaving the rest of the interior baking. The placement of the exhaust pipes optimally located to cause 2nd degree burns on your shins when loading groceries. The design that screams form-over-disfunction.
