At first sight there’s a point to be made here about trust in institutions that you’d think “Well surely if this was dangerous it wouldn’t be allowed” or something, like if this was a tourist dive bell that went wrong I’d argue I wouldn’t get in it because I have 0 trust in institutions but your average person, yeah sure.
Hell I’d extend that even to the “in case of death we ain’t owe you shit” waiver as those seem way too common. But at the point where it says “the submarine is not tested or certified by any regulatory body” in plain text and you don’t have some sort of mental disability that’s on you, that’s entirely of on you, if the words “untested, unregulated submarine” don’t register to you as “stay clear” there’s nobody left to blame and also it’s hilarious
