I recently saw a video of a drone. Unremarkable news, you may scoff. But this wasn’t just any drone. This was a rather large drone (as drones go). In fact, this particular model was a person carrying drone, complete with a central ‘pod’ just big enough to hold an adult human comfortably. “Finally!” I thought, “Here is the flying car I was promised by all those Hollywood films as a child!”. Alas, things were about to take a bizarre turn. The drone had no controls. No central steering wheel. No airplane-style ‘stick’ protruding from the floor. There wasn’t even so much as a sign on the wall stating “scream if you want to go faster” – how on earth do you control this thing?
