It seems that if the Mavic is in auto-track mode and you are moving towards it the unit must necessarily fly backwards since the camera cannot view to the rear (or at least that is how it appears from looking at pictures of the unit.) If this is the case then it seems possible to accidentally back the unit into a tree or wires or other obstacle when auto-tracking in this manner since collision avoidance only works when moving forward. Am I missing anything here? And yes, I know that in theory you should be able to see and prevent such a collision, but then again in theory you should always see and prevent collisions and as we all know that's not necessarily what always happens in the real world. Not a show-stopper but just noting it.
