While watching the recent Patrick Long movie that Chad Plavan posted I noticed that he has a lot of steering wheel movement even during a constant radius turn. I have noticed this on other videos with other drivers. My question is what does this accomplish (I really don't know just trying to learn here).
The car does not seem to be responding to the inputs (ie) the line stays straight even with large movements. This would make me think the car is pushing and he is trying to get it to hook back up by removing some steering input.
I have tried this myself (so many do it it must do something) in some pretty hard turns and find it doesn't really do much to help the turn. I usually try to keep the wheel inputs as steady and consistent as I can and purposefully try to avoid what I am seeing. (I am however slow)
The man didn't get where he is by accident so there must be a reason for this technic that I don't understand.
