Workhorse (WKHS) has been testing its truck-based drone delivery system every day since it received an exemption from the FAA to do so in early December. Stephen Burns, CEO of Workhorse (WKHS), said drone delivery is coming, but the government is taking it slowly. 'Delivery trucks are ubiquitous so a driver can jump off that truck, maybe a mile or two away, and watch the drone,' said Burns. 'That’s the way you ease into something.' Workhorse manufactures medium-duty, EPA-approved battery-electric delivery vehicles and fully integrated truck-launched, FAA Section 333-exempt unmanned aerial systems (UAS) delivery drones. Amazon (AMZN) has also been cleared by the government to test drone delivery for its products. Nevertheless, the e-commerce giant’s drones would be forced to fly from warehouses many miles away. It’s that loss of control in heavily populated areas that has the government worried, even as hobbyists can use their drones without much restriction at all. 'The FAA has been trying to regulate commercial drones for six years and it’s an interesting thing when technology outruns the regulatory process,' said Burns.
