The problem is with your cell phone bystanders “can visually see you” – the operator – and judge you, your body language, your mannerisms, etc. to logically deduct if you are using your cell phone appropriately (or not) given any chance meeting or yourself noticed by others. With drones, there is none of that and the fear automatically jumps to intent of invasion of privacy.
As an example, it’s known that unless the face of robotic humanoids APPEAR 100% human in the face that bystanders whom visually see such high technology **will not** trust it. This is the same challenge and problem drones have set against them from those not familiar within the industry.
