Because there main purpose will be on the transportation; another good thing I observe in Deep Aero is the environmental impact of their operation. Because they will use battery they are virtually zero CO2 emitting company. It has large effects on improving air quality most especially in the City. Many environmentalists will be in favor with this project.
Nice one mate im glad that you see this side, in fact there are many motorcycle company are planning to build a battery operated bike to help lessen the pollution in many city... Good with the deep aero they already think about the environment coz they can also build drones that fuel operated to prolong it used but they choose battery drone for the sake of the environment...
