The above link is a video showing me trying to get my
mavic 3 and evo lite+ to hit eachother, at least where they have obstacle sensors. I used the front ones for this experiment. This experiment wasn't a test of high speed approach, it was a low speed test. I wanted to see if the drones would see each other and stop. THEY STOPPED EACH TIME. Or, they tried going around each other. I could not get them to collide no matter how hard I tried.
I might make a higher speed collision risk video, but I don't know if im brave enough. But I expect they will avoid eachother or break. Breaking would be bad though. I would have to set them both to AVOID obstacles.
Why am I posting this video? It shows that even if the skies were cluttered with drones, especially ones with 360 obstacle avoidance, they would likely bypass each other.
