This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.
I had never seen one of these before today. They're great. Way better than reaching for a single pole in a crowded car and wrapping your hand around some stranger's fingers. And If you have the whole thing to yourself you can hook your arm through it.
I'm not sure it'd be worse than hooking your arm through a single pole. Presumably in that scenario you're trying to stay put, right? If you're getting shoved hard enough to break your arm by being yanked off the pole you're getting shoved hard enough to crack your skull against one as well.
Realistically, the only way a commenter train is going to change direction or decelerate that violently is if something derails it or slams into it.
Trains like this don’t slow down very quickly, even if you pull the emergency break. That’s why people are allowed to stand, walk, etc.
