I dont think he is not caring . He is just not blindly running over them. We are getting close to 50 hours on our pair of sparks and I can tell you the shallow rivers we ride on are infested with floating sticks weed balls,hull smashing stumps, shallows and rocks. Just focusing on not driving over most of it has seemed to work for us and so far no damage to the jet drives or hull. Of course now that I said that I wont make it away from the dock next trip out.
The only thing I find spooky about this video is he is riding alone which is something I would never do on the water.
