Hmmm - this debate is taking an interesting? direction now, however, can I just explain my personal preference (and each to his or her own), but when I drive a car on track for a really fast lap I use the kerbs. Despite wearing a six point harness and homologated race seat (because it has to be as I am talking about my experience as a club motorsport competitor) I still move around to some degree as the forces can be quite extreme and sudden, so a throttle pedal that reacts too quickly is, for me, a definite no no ... hope that makes sense and I hope no one takes offence, but that is the reality on the track for me ...
