*facepalm*
You clearly didn't read my post. First paragraph clearly states points that are nothing to do with racing round mountain passes, but that are applicable to every day commute driving.
Go and watch all of Reg Local's YT vids, you'll notice that he's not remotely racing anywhere at all, but rather takes a more IAM-based (well, ex-police pursuit really) viewpoint on driving. Everything he mentions there will improve every aspect of your driving far more than even 100bhp more will. His books are good as well, but the videos explain it rather better. If you can't see how any of that would assist you as a driver, then I don't know what will.
Power is nothing without control.
