Who wouldn't want to see that?!
The people that live there and have seen it before. The people that have visited seen it and been trapped by it before. It is awesome in its unrelenting flow to the sea, it doesn't matter that there is a road there, it will flow over the road, a house in the way? I will flow over, or in one lucky case around the house to reach the sea.
It really is an awesome spectacle to see. The sound of it sliding over and around and the trees tumbling in its path, the sound of cars being pushed, and exploding. Then there is the sound from when it reaches the sea, the steam and the heat and the mist of the vaporized waters.
One has to be so careful around the living flows. You have to know that you have a way out, that your path is not going to be blocked. It does move slow, you almost always have time to get out of the way, but you just never know when an old tube will open up.
All that, it is still something to really see and experience in person. Oh also you can ski at Mauna Loa ski resort if you did not know, and it is real snow, not man made.
