Why with dji being the leader in drone products haven't introduced a sensor array for any of their products for avoiding obstacles? As far as I'm concerned that would make a lot of owners happier with their product lines! The advancement in technology is there and dji proven it over and over again and again with the latest products you put out! So not only once you dji get ground station and autonomous flight is ready you can work on a nice obstacle avoidance system! Just a thought!
