you can realistically be as careless as you can with any other cell phone.
Hahahahaha... Right, right.
Something with a hinge can be treated the same as a bar where the glass is surrounded by plastic, say a Pixel? I don't think so.
"Realistically", something like this will always be a compromise on durability. There's simply no way for something that bends in half to be "realistically" as durable as something that doesn't.
Hell, I have different regular phones with massive durability differences (one is glass, titanium and ceramic, the other is all plastic), and none of them have a hinge (let alone a foldable screen). Which one of my phones is a folder as "realistically" durable as?
Let's see the testing from the screen manufacturer defining how many folds the screen can do before a crease becomes apparent, or a pixel is lost.
Now let's see the same test stats for a non-bending screen. Oh, yea, they don't have that kind of durability testing, because they don't have wear from bending.
You may wanna look up what "realistically" means.
Edit: so far 9 11 morons have shown they don't know what realistically means
