Some visitors come often—close friends, regular delivery people, tutors, drivers, repair guys. If you quietly note the licence plates of their bikes or cars somewhere, you start to recognise familiar vehicles at a glance.
So if you spot an unknown vehicle parked outside your door at odd hours, or hanging around repeatedly, it stands out more clearly. You’re not paranoid, just aware of what’s normal and what’s new.
It also helps you confirm quickly, “Haan, yahi driver hai jo usually aata hai,” instead of relying purely on memory of faces.
