Re: It's a good thing....
"Now put one of those people in the "exciting" position of trying to photograph or video a tiny object in the sky, often under poor conditions..."
Exactly this! You're not expecting to see anything unusual, so it takes a moment to realise that something's afoot. Then you have to stop being gobsmacked long enough to think of taking a pic video. Rummage in pocket/ bag for phone and get to the camera app - yes, I know, camera hotkeys etc. I disabled mine cos they kept sprouting the camera when I didn't want it. Then you have to point at the object and shoot. You can try the last bit using an aircraft at night as a substitute UFO - chances are all you'll get is a wobbly set of bright lights against a cloudscape, if that.
You could try a further experiment; secret your phone about your person in its usual place, then walk along a busy main road with a friend. At random, your friend is to point out a passing car and you have to get a good picture of it before it's out of sight. Tricky.
Naturally, this latter experiment is inappropriate for the dickheads who routinely walk along and even cross roads with their eyes glued to their phones because a) the UFO could land on their head and they still wouldn't notice, and b) I doubt they have any friends.
