I hate being negative, but I feel compelled to respond with negative comments. So I will ignore my mother's advise (if you don't have something nice to say, say nothing):
1) PLEASE follow the FAA rules for recreational flying. If you do not know what they are, please read up on them. Hint: flying over traffic is illegal. Considering you had joined this forum back in Jan 2019, my bet is that you do know the rules and are simply choosing to ignore them. It is people like you that are just making our hobby even more challenging as more regulations and public opinion come down to bear on the rest of us.
2) You were extremely lucky. You could have a major crash and even lost your drone in the tower or high tension wires.
Here the full context. I live right next to a very large school, and this was during the off seasons, and the entire parking lot was empty.... so I was at first attempting to drive around in the parking lot to test out the OA features of the MAVIC2, in my years with both versions of the Mavic I've never tried it tracking a car even though plenty of youtube videos of people doing exactly the same thing. Since this was the last final day of the entire decade I figured now would be as good as time as any. So I started slow and cautiously, putting the drone in the "SLOW" mode of the active track, and I at first wanted to maintain an floor height of at least 225 feet which would give plenty of clearance but the active track 2.0 was not smart enough and would always lose tracking after just a few seconds of my car moving... even though there were no other cars there to confuse it.
Finally I had to get the drone to get very low compared to the ideal height of 225feet in order for it to sustain an active track lock on my car, as I spun a few around the parking lot my thought was to do a quick circle of my immediate neighborhood area, and it wasn't until I came to the corner turn that I realized there was a tall tower there... immediately I attempted to force the Mavic to raise to very high attitude but to no avail, before I even had chance to cancel the active track it had already struck.
This is DJI's fault because
1) It pitched the "slow mode" as 360 degree OA and made it sound much more confident and safer
2) The Mavic refused my commands to manually go up higher
3) The mavic still hit something when in broad daylight and going slowly and all sensors were being used
4) DJI makes it impossibly difficult to export the logs after the crash... (see above)
5) DJI active track is crap compared to skydio 2
6) Active Track 2.0 basically not working at reasonable heights and only works when very low tracking object, had DJI active track worked while at 200 feet or above this wouldn't have happened.
7) I had it track me from BEHIND but as my car turned the DJI MAVIC orientation changed on its own to the RIGHT. Had it stayed behind me like it should have, again none of this would have happenend.
This is like Boeings MCAS bug.
This was my very first time using OA in Mavic to track car... Had DJI published warning that for whatever reason during this OA/Active Track that it may be that height increases are IGNORED. and inputs to gain height are simply not followed, then I would have had a reasonable heads up and then proceeded accordingly.
In all my years of flying Mavic I've never encountered any instance of a height input being ignored other than if it was a NFZ alt restriction and this simply wasn't the case here....
Again, a flaw like this is like the MCAS issue that the Boeing 737MAX faced.
