Your iPhone can automatically drop a pin in Apple Maps when you park your car. iOS derives this through your connection to your car audio system, based on Bluetooth or CarPlay. When you unplug or turn off the car and walk away, the location you left is where your iPhone thinks you parked your car.
However, this feature may not work for you like a family member did. In fact, they couldn’t even find the option, which is usually in Settings † Cards as Show parked location†
Apple mediates this feature through privacy settings. It requires you to have Settings † Privacy † Location Services turned on and that Settings † Privacy † Location services > System Services † Important locations is also set to on†
The reason? Apple infers important locations for you through many signals and stores them in important locations. It distracts your home, work, school and other important places that you visit repeatedly. iOS doesn’t drop a pin on a frequently visited location.
The idea must be that the feature would be annoying to people with that feature turned off, as they would drop a pin every time they parked in front of their house or in a work parking lot. So Apple doesn’t even make it available.
