Drones are aircraft and the operator is a pilot. In the case of a "follow me" drone, how does the operator maintain control of the flight? There is a requirement to avoid flight over people and yield right of way to other aircraft. Drone operators have the rights and responsibilities of traditional pilots, and if you refer to a drone as a "toy", you may have the answered, in the negative, the question of whether to get one. Drones are aircraft in the same sense sense that bicycles are ground transportation and likewise need to be taken seriously. Both, of course, are also fun.
