Absolutely! When I have ideal conditions (lighting, track, racing division, etc) I start out in "safe mode" where I know my settings will give me excellent or at least very good results. I will then switch to "risky mode" in the hope of capturing a few stunning images as well.Quoted for the truth!!!! I have NO reason but to try stuff because I only have to please myself. Two weekends ago I tried the same stuff and completely messed up the pics, boy was I pissed when I got home I should have known better but "You can't fix stupid". SO last weekend I thought WTH I have nothing to loose I'm gonna try it again, some worked others well........ Didn't, LOL.
Again all of this depends on the type of racing you are shooting and the purpose of being there.
Yeah, I've had more than one of those, "You can't fix stupid" events too! Just pick up the gear and go do it again!
