I'm not so sure about this. If we apply the same logic to cars, it's immediately obvious that almost everyone understands this concept quite well -- jumping out of a moving car is dangerous, precisely because you'll be moving when you hit the ground.

I think they're underestimating how quickly the boat is moving, and how quickly you'll slow down when you hit the water.

I don't think people realize that water is H A R D when you hit it above a certain speed. No different than belly flopping off a bridge and completely disintegrating your innards.

It's transferring known data to a different situation that people don't seem to be doing at all.

Yes, exactly. People know the street is hard. People don't dive head first into the asphalt on the regular when they're standing still.

They don't expect water to be any different when going fast than when not.

And, like, obviously people have a sense that getting out of a speeding car is dangerous. They intuitively know that the road is speeding past them and that that speed differential will cause pain, injury, or worse. But I don't think they really understand themselves as a moving object in all of that.

The car is moving fast, and "getting out of a moving car" is dangerous, as opposed to "being a high velocity object" is dangerous.

The mental model is different, and incomplete, so some things seem like they should be possible when they're not.

People understand you'd get hurt jumping out of a moving car (even still, people sometimes try it) but often underestimate the amount of force a vehicle moving at various speeds can apply. Huge difference between 30 mph and 60 mph.
