I almost always collapse my cane if I'm sitting or hanging out for any length of time. If I'm waiting, or expect to need it quickly, I may just balance it between my legs, but it's rare that I don't fold it.

Since I’m not a sheep, and don’t follow the NFBs twisted Philosophy of “If you use a folding cane, you are trying to hide your blindness”, I simply fold it up and tuck it out of the way.
On a bus/train, fold the top 2 segments Down and either put it beside me or between my legs.

I use a streight cane. I like the feedback I get with its construction. Some people don't know, but the NFB gives thousands of free white canes every year; they are streight canes, if someone wants a collapsible or telescoping cane they have them in the Independence Market.
My cane is 63 inches tall, and I find it easy to place it along the side of the cars i freaquent, I can place my cane by the wall when I'm sitting down somewhere, or I have no problems with keeping it laying across my shoulder as I'm sitting.

If it's for only a short time I trap the bottom end between my feet and then between my knees. If it's for longer than a few seconds I fold it up, and yes, that's partly because I don't need an enormous antenna advertising my strangeness to everyone who walks by, and anyone who doesn't like that can do one. I have a complicated life, I don't need it any more complicated.

I fold it up and put it in my holster.

I fold it down and then keep it near me.

Holster it.

That or put it back in my carrying space I designated for it on my backpack. ( Basically the water bottle holder, because it comes with a strap to help hold it down. )

I highly recommend having a backpack for that reason and others. Beyond the general usefulness of keeping things in a bag, it can specifically house any medical information and equipment.

Given my low vision blindness and diabetes, I have a lot of crap to lug around.

I fold it.

When I’m on the bus I fold two of the segments on top and use the string to keep it like that. I don’t have to worry about people mistaking it for a support pole and i am still identified as vision impaired

Lean it on a wall or in a corner if it’s my non folding cane or, if there’s no other choice, put it on the floor with my foot on top and angled so it’s the least risky to anyone walking by (it’s very long). Putting it in cars is tricky and has to be done tip first so I can slide it partly into the door well in the front seat (if I’m in the back). If I’m in the front seat, the handle goes in first, over my shoulder, so I can get enough room to pull the rest of the cane in. Usually I have my dog or a folding cane, both of which are easier to manoeuvre. Folding cane is either in my lap, in the seat next to me, or on the floor under my chair. Dog just lays down next to the foot that has the most room beside it, gets tucked under a seat, or curls up somewhere in a car.

Fold it up and chuck it in the shadows. Then when standing up casually whip it out like a lightsaber. Its an intimidation factor and a power move.
Lol no but seriously I usually just fold it and put it on my lap or the floor under my chair til I need it again. Having it out is kind of annoying since you gotta lean it against yourself or a wall nearby and that could trip people too so just fold it and avoid any of that.

I make it lean on a pease of furniture or lay it behind my butt.

As much as I prefer the feel of my rigid cane, I almost always use my folding one out of convenience - so I fold it and put it back in my bag.

This is just common sense...if it's a folding cane, fold it and store it near you for easy access. I usually drop mine alongside my chair or under my chair. If you have a rigid cane, lay it on the floor and be cognisant of traffic around you. It's really fairly intuitive...
