So then..why do rally drivers use it all the time and are slower if they don;t?
Road use: is a different method of use much of it just for confidence but that makes for faster but yes. you may be right poor use is worse than no use. Much of true speed somes from confidence but you won;t make top grade nowadays without it (in my experience)
With much respect, get it right and it works and cuts times (more so on loose surfaces) but like I said, you'll need to find your own way.....pratcice practice practice.
Ever heard of Rallycross?
