Sorry, but subject tracking and Tap-To-Fly are gimmicky and for noobs! Any experienced pilot won't have a need for this stuff. Even obstacle avoidance is mostly rubbish for well-prepared flight plans. However, an optical zoom and 1080p FPV is something that EVERYONE would find useful --- not just the new people coming into the hobby who need lots of safeguards to make sure they dont crash their new toy. 99% of these newbie hobbyists are too ADHD to RTFM and practice becoming good pilots. If Inspire 2 has both optical zoom and 1080p FPV then I am tossing my P3 Pro in the dumpster and upgrading so fast it'll make your head spin!
