You lock your car with the remote, then you enter the mall or restaurant. After 10 min. you start asking yourself if you locked it or not. You just can’t remember. After a fierce battle between “I did lock it” and “I didn’t, someone will steal my car” you decide to walk back to the parking lot to lock it again.
Car makers should include some kind of indicator on the remote that can tell you at any time if you locked the car or not.
