OK, but the point is, it doesn't fix any problems either. But it does create them, if drones have to travel 2x as far by following roads, which wastes energy, limits range, and requires flying more drones to achieve the same level of e.g. deliveries. The larger point is that property owners don't have a legitimate reason to ban drones passing 200 ft over their house. If they're bothered by noise, why are they going to be any less bothered because the drone is flying 50 ft away over the road at the end of their driveway? If they're worried about drones falling out of the sky, they're still going to be bothered about their car being hit during their entire morning and evening commute.
