So, will the P4 go to "Sport mode" speed on-the-fly? Done w/a switch on the remote? Don't know...asking. Yes, I agree Airspeed can be a major player when flying in 20 mph winds....which sometimes equate to 25 mph winds @ 400'. But, if we can change the speed restriction of the P4 on the go, I'd settle for no collision feature while ferrying. Turn it back on when coming in to congested area....if that's possible. Don't know...just asking.

I'd like the tracking feature for the type of photo work I do. It would give me more efficient use of battery time & less time needed to position. This is assuming I understand how it operates. Maybe I'm working w/misconceptions.

I also like the newer gimbal suspension method, and the fact that the data card for the photos is stored in the side of the drone vs the camera itself. I always carry spare cards & change them out immediately when putting the drone away. I down load them later when I have time.
