Auto dipping wing mirrors when you go into reverse (I had this on a Lexus LS430). It tilts the mirror and shows the kerb/rear tyre position. Saves you scuffing the kerb and reverts to pre-set position (or can be switched off).
Auto dimming of internal rear view mirror (and why not wing mirrors as well?).
Sou'wester, for opening the boot when it's raining
