Here&#x27;s something I was thinking of:<p>1. insurance<p>2. detect objects and avoid them.<p>3. standard flying height<p>4. register unmanned flight path<p>5. communicate with other drones near by<p>6. small fee to manage flight path registration<p>7. if engine goes out some way to recover and land safely<p>8. way to manage privacy for sensors.<p>9. real time reporting of location height etc.
