There's a real sense of accomplishment that comes from learning how to nimbly pilot a drone. Unfortunately, that's also frequently accompanied by a nervous anxiety stemming from the potential for your pricy flying machine to smash into a tree, mountain, building, or any other hard object. Luckily, modern drones have obstacle avoidance tech inside to cut down the chances of collisions, and DJI's new $799 Mavic Air is chock full of sensors and computers to keep your craft in the air and out of the "drone fails" section of YouTube. DJI announced the Mavic Air at a press event earlier today in NYC. It was the public's first chance to see the revamped guidance system, which works similarly to a self-driving car.
