I live half the year in a ski resort. Full of the gopro target demographic. I sometimes go skiing and drinking with these folks. Mostly 20 somethings who, upon finding out that I'm a drone enthusiast, start asking the usual questions. And like all off those with zero drone experience, be they default extreme sport types or regulars, they start asking about follow me. I explain that it has no place on the mountain unless it's under controlled or empty conditions or when the first fully capable, 1080p minimum, palm size altitude hold GPS drone is released. Until then forget it. And the few of those guys who take time to come out with me agree at the first minute they see a standard size drone operating. Beach goers worldwide complain about drones. Imagine a ski slope with just a few flying around. Then add lift cables and the like to the mix. Interesting in theory, a nightmare in practice when numbers are involved.
The other issue is how much disposable funds these extreme types possess. Mind you, back in my twenties I did plenty of BMX and surfing. Didn't have a bucket to piss in either. There are always exceptions but in the high end ski resort live in, the price of a good phantom is a lot steeper for the folks who frequent the jumps part of the slopes than it is for the thirty and forty something folks at the apres ski.
Hence, until a truly cheap, reliable, 15 minute plus battery, GPS, altitude hold palm size drone is released, follow me is a gimmick at best.
