The Federal Aviation Administration has released new and looser rules for flying drones over highly populated areas and at night, effectively laying a welcome mat for future aerial deliveries of takeout food, Amazon packages, prescription drugs — you name it.

Why it matters: While the prospect of Jetsons-style convenience with less street gridlock is tantalizing, there are still plenty of logistical hurdles, and it will take some time for cities to figure out how to manage low-altitude air traffic as routinely as they do today’s road traffic.

Driving the news: FAA rules — handed down late last month — will require drones flying over cities to use remote identification technology, so people on the ground can tell what they’re doing and who owns them.
