The Griff 300 octocopter can care 500 pounds of passenger for 45 minutes of flight time. It weighs just 165 pounds.

The drone is controlled via radio remote control from the ground. Those with the extra cash also have the option of adding a mobile control station, which allows for the drone to be controlled in the first-person view. The drone also has a variety of other add-ons that make it suitable for a number of applications, including search and rescue or firefighting.
I think that the tin cabbie from James Blish's 1957 story Cities in Flight is a pretty good prediction of the Griff:
The cab came floating down out of the sky at the intersection and maneuvered itself to rest at the curb next to them with a finicky precision. There was, of course, nobody in it; like everything else in the world requiring an IQ of less than 150, it was computer-controlled...
The cab was an egg-shaped bubble of light metals and plastics, painted with large red-and-white checkers, with a row of windows running all around it. Inside, there were two seats for four people, a speaker grille, and that was all: no controls and no instruments...
