Unlock on approach disabled here for the above reasons - I hate the constant "lock/unlock" when in the garage near the car and not intending to enter it. My car is always locked when I'm not in it, and you don't need to live in a war zone - you just need to live in an area where other humans of any size, gender or description live capable of getting in your car. As pointed out, you have to put your hand in the door handle to open the door regardless of the setting, and when you do the door unlocks. The only possible benefit(s) to the door unlocking automatically are 1. if you routinely park in a dark garage/area where the pathway lighting is helpful as you near the car - it won't come on until the door(s) unlock, 2. if you routinely find yourself burdened with carrying pets, packages or relatives and you can't physically unlock the door (although you still need to physically insert your hand to open it, when it will, as observed, unlock), or 3. if said burdens (with the exception of packages) want to get into the car a few seconds ahead of you, the driver, although the door handle would present a barrier to the normal assortment of pets, with the possible exception of kangaroos, ursinae and simians.
