I had the same thought seeing the hero videos on this page displaying beautiful mountain scapes and vistas - I wouldn't want to be the person disturbing this space with an intrusive drone.
I read over their product page and, like always, I'm absolutely amazed that these things exist now and can capture such amazing video and photography at their price point. I'd love to get one to use.
But I won't buy one, because every time I go out now to the beach or on a hike, I see people with things like these and I just cannot stand them. I hate the ridiculous noise, I hate the fact that these people are filming things in the middle of streets and sidewalks and trails and generally putting themselves in the center of everything and inconveniencing everyone else just to 'get their shot'. I hate the idea that I am potentially being filmed by some random kids with a high speed camera on the drone hovering out over the park bench I'm resting on.
And because I hate these things, I will not buy one, because I do not want to turn into the annoyances that I feel, no matter how cool the tech looks.
That... or... I'm secretly afraid that I'd buy it and not actually have anything cool to film and it'd sit in a closet and be another $800 paperweight device.
But let's go with not wanting to be an another annoying 'Main Character Syndrome' person and just be quiet and peaceful when out and about.
Walked down the edge of canyon in Jasper National Park today and you had to wade through people taking pictures (admittedly, myself among them). What is the difference between someone taking a selfie with a phone and photos at 50 spots along the edge of the canyon, and someone flying a drone at that point?
The phone doesn't make noise, and cannot fly everywhere around in a 2km radius. The phone owner has to walk there. So if you go hiking in places where fewer people go, then you get fewer tourists. Probably you don't want to get drones there (I don't).
I do not think that there are ICE versions. But there are many different versions by now, including pump foil (just up-and-down body motion), SUP foil (with paddel), surf foil (wave), wake foil (towed behind boat, but able to let go and just surfing on the boats wave), wing foil (inflatable sail that you hold in your hand, the most popular version) and versions for kite and wind surfers. All are currently significantly cheaper than eFoil (starting around 1k compared to 5k for eFoil) but mostly more challenging, in good sense and bad sense. Some people have said that you learn how to eFoil in 30min. Then the battery is empty. But that is okay as by that time it becomes boring. Which is different to all the other foil sports (exept maybe wake) were most need ~10h to even achive small steps forward. But once you manage, basically every body of water becomes a surf spot.
A very few very selected nature parks with no-fly zones aside, most suffer more from GA with engine, cell, wing and prop designs literally dating back to 1955 (Cessna 172), than they'd ever from drones operated by responsible people.
