Looks cool until the guy in front of you crash then all behind will crash too. Ride the train is the same as crashing like a train.
Control is important. You have your comfort zone as a newbie starting out. Just like when I started out skiing and when I was going slow to medium speed, I was enjoying it but then it got faster and faster and I realized I don't have the experience and not knowing how to slow down, my mind will trick me and it got scary. Like riding that lift, I missed jumping off the beginner area and it took me way way to the top of the peak. By myself, wind was howling and looking down like straight drop, only way was down so what I did? I got to my azz and slid down slowly. Then I saw other pro be zipping on by and I got embarrassed so I mustered enough courage and down I went and it got seriously fast but by putting myself in that zone of the moment, I got better. I got back up there again and to slow down with skis, all you have to do is the hop right hop left while using your stick as balance and you will slow down enough to enjoy it.
So yeah, that mountain bike trail in that video, you can not go slow. You need to go full speed to catch air or you will not make it to the next mound. One mistake, one fall and you are done.
