With the majority of manned aircraft t 500'AGL and above (police, fire, EMT/LifeFlite, and news helicopters; agricultural aircraft, and military) all routinely operate at 500' or so... I really think the most reliable way to consistently separate manned and unmanned is altitude. I'm of the belief it's not if there is a 400' AGL restriction nationwide for all non-commercial sUAS/UAS, but rather when.
