Seriously, couldn't they just extend the tube a bit so it overhangs the exhaust pipe???

Oil doesn't expand and steam like water, so no that won't happen, but hot oil leads to very nasty burns and can melt gloves onto your hands. Most bikes run the oil around 200 degrees. So no it isn't safe to change hot oil. Don't do that.

And, specifically because oil doesn’t boil at those temperatures, it can be at much higher temperature than water can be as a liquid.

We tend to have a mental model of how much damage water can do at its “max” temperature, because liquid water stops existing after a certain temp.

But oil can be so much hotter than that, and still just be a liquid. It’s dangerous in that way, because while a drop of water at near boiling can only do so much damage but a drop of oil can be holding a lot more heat and hence cook a lot more of your flesh before it runs equalizes with the surroundings
