Add ability for user to turn off headlights on unlock, at least when at home. It shines them into my neighbors' windows every time I come close to the car with my key in my pocket. For cars with a key fob or Bluetooth proximity unlock, accidental unlocks due to proximity at home or elsewhere can be prevented by carrying the key in a foil bag or by deactivating passive entry. However, I like passive entry rather than clicking the key every time, and I don't want to hide my key in a bag.
