For cyclists, a drone to fly in front of and behind you to warn of upcoming danger. (via Fast Company)
Doing a quick Google search tells me about 700 people every year are killed on a bicyclist being hit by a car. That doesn’t count all the people (like my brother) who are injured but not killed. Having a drone could warn you of danger but having a drone flying around you would increase your visibility.
