Though UAVs have begun to enter the commercial space, the future for them still has significant uncertainty: Today, UAVs require skilled operators for actual use, and have a high crash rate, factors that will slow down acceptance in various end applications. UAVs also have technical obstacles due to issues like low electric range, lack of true autopilot, and basic airworthiness, but the authentic main obstacle is the chaotic current state of regulation: While countries such as Canada and Australia are ahead of the game, with regulations in place and commercial flight actively happening, many countries have little or no meaningful regulatory structure, putting the UAVs awaiting the parliamentary "green light" to take off.
