Hello; At 5:19 this is on level ground, tilt you device so that the trees are growing straight up and you will see, it is a trick of holding the camera at an angle. This is dangerous, I think these machines should be controlled by a Remote software, and the driver should not need to sit inside vehicle. If you tip your camera enough everything looks worse. See 3:46. Or maybe those are some new kind of tree that grows sideways. It wasn’t dangerous at all . Loser set the camera on an angle. Look at the the Trees in the forest all growing at a 45 degree angle to the left. I call B/S on that one. Excavators are the most abused heavy machines in the world. I recommend legal actions against its abusive use. Some are building road on the Clift high up in the mountain. Somebody has to dig road where we're hiking trails. But you can be these guys are making 200-300 buck a hr. The new road for the over pass will cost a few million.
