Let's say you own a BMW and you park it diagonally across four handicap spaces, but can't remember exactly where you did that. Whatever do you do? Well, if you have an Apple Watch, it can remember for you.
As part of the hoopla that is surrounding the Apple Watch (which you should be following on Gizmodo), Apple has partnered with a number of people in order to increase its usefulness. With BMW, Apple is using GPS to help you remember where you parked your car.
It seems pretty basic. When you park, the car drops a pin in your watch's map, and then when you can't remember where you parked (who forgets where they parked?), just go to the watch, and it'll guide you back.
Could be pretty clever.
