I would like to know more details about the new "tracking" feature on the P4. How good does it really work? I have seen the videos of people dressed in bright colors, over a dull floor and it seemed to work. But how well is it going to work in a realistic, or every day environment? Tracking is one thing if everything works out, but what happens if the P4 loses track? I believe it will just hover, right? If that is the case, the whole tracking thing seems pretty stupid to me. Here is why: Imagine you are riding your bike down a mountain trail. The P4 follows/tracks you. It loses track and just stops, hovering on one stop. How the heck am I supposed to know that it stopped? Am I supposed to look back every 30 seconds? Do I have to have a spotter riding behind me? Same goes for any other scenario where the P4 is tracking you. Somehow one needs to be aware that tracking got interrupted, so you can go back and "get it". Maybe I should say "take over control again. Anyhow. Seems pretty useless and limited feature when doing it alone. On the other hand, having someone follow you is not the worst thing in the world. Actually, JUST following someone on a bike is watt easier than following someone on a bike WHILE trying to film them as well, ha ha. So maybe the tracking feature is not that bad, useless and stupid after all? What they should have done is, have a GPS on the person that is being followed, so that if tracking gets interrupted, or something gets in the way, the P4 can regain tracking and continue following... Just a thought. Thanks.
