You scan the area, the distance to your car. Extra cautious if it’s early morning or late at night.
And vice versa; if you park your car in your driveway or parking lot near your apartment, you wonder how quickly you can make it to your door without being noticed. You wonder who is watching and what they might do if they see no one else is around. You hold your breath as you damn near run after locking your car, keys prepared to unlock your door as quickly as possible. You make it inside and automatically lock the door behind you. You do this several times everyday.
