doing all your braking and downshifting before the turn gets you in optimal gear...you should know what gear you're in when doing this. If you don't, you're passively driving and should engage the auto-drive setting for auto-shifting

I know it seems really basic, but a good refresher. Gotta keep your head in the game as if you were driving a motorcycle.
