None of that is relevant today. Cameras are everywhere. External cameras, GoPros in cockpits.
Ball lightning stories disappeared with mobile phones. Ufo stories are also disappearing. It's less and less likely that everybody just happens to miss opportunity of taking pictures.
Not really. I don't even have a camera on my car and most of the people I know don't either. Even with the accessibility of cameras it's hard to capture events that take place in a small time interval. That's why when someone sees something momentarily spectacular (like seeing a person throw a basketball into the hoop from behind their back at half court) they say things like "I wish I caught that on camera"
Camera's are definitely everywhere. Recently a meteorite struck Belgium. Lot's of videos and around 200 people testified of seeing it.
The difference can be lots of things of course: densely populated, maybe seen from further away etc. But it's indeed peculiar that now in the smartphone age, we hardly see any UFO's on video, relative to how many camera's there are.
