I could do with a weather drone that goes off on its own before I leave home to tell me what the current weather is in the local area. When not in use it could be programmed to automatically water-bomb London cyclists.
Do you realise people build high altitude balloons with a GPS and camera that can float up to the edge of space before the balloon bursts and they plummet back to Earth for retrieval the next day? I'm not sure a toy drone poses any more of a risk.
