content: It's very difficult to get a private pilot's license. The assholes will sell very small 'ultra-light' type vehicles and call them 'cars' to get around the license restrictions, but people will die, and the shit will get banned. The problem with robots and flight is still an energy use problem, the problem is the energy required to move a man is not worth the cost, better to have nano-bot fly's that just fly in swarms, and licensed like drones. Space learned long ago that human flight is worthless, and humans on earth will learn that its better to wear a virtual reality head-gear and enjoy the thrill, but the actual cost of human flight is not worth the cost.
