It takes alot of skill to drag.
Before I started, I had no idea what I was doing. Actually for a good few months of doing it I got the hang of it properly however, I didn't make as much progress as I wanted to.
To people who haven't tried to drag and assume it's easy... It's not. I used to drift alot back in the old days of gt5, and all it required was timing and controlling the throttle and handbrake.
With dragging its completely different.. I am still learning things that I can improve on to make my cars faster, but there will always be someone faster, even though most dragsters hate to admit that.
In Gt5, dragging is the most underrated, competitive sport you can do. When you finally see how long it takes to make that "perfect" tune, you realize how much time you spent on it. It's ****ing very hard to figure out, alot harder then circuit or drifting.
