As an advocate of Health and Safety at work for decades I have to say any risk is not worth taking but it's all a matter percentages and quality of life. I have been driving a motorbike and a car for many years, on and off, in Thailand including principal cities, up the highest mountains and most remote areas. My risk of injury or death was a thousand times more likely than been hurt by drone. To me I loved the risk of driving motorbikes, cars and flying drones from my hand. They are also a means to an end. I took a great deal of care and planning but the thrill of calculated risk was to me, worth it. These are risks I take that only affects me, I will not endanger others. But again, it's all a numbers game. On very rare occasions I have flown over people but the risk of them being hurt was minuscule.
