Sorry you got downvoted, I used to think the same thing. And before TikTok, that’s what I would do. Just bring cargo shorts with a zipper pocket for my stuff.

But people just take it out and try to film, and it’s really common. Which is a dumb idea because it’s going to come out looking like shit. And turn into a deadly projectile. People don’t realize how intense some rollercoasters can be. They can pull up to 5G of vertical, a couple Gs lateral, and a negative G or so of airtime, and it transitions between these forces quickly making it easy to drop the phone.

The parks all make a professional POV videos for each rollercoaster where the camera is bolted to the chassis of the train so it’s stable and you can actually see what’s going on.
