The narrow slot allows the phone to stand vertically in a convenient position, making it easier to see and retrieve when the vehicle is parked. It also means your phone does not have to occupy one of the cup holders, leaving both spaces available for drinks. For drivers who regularly carry a phone and beverages, that tiny piece of plastic can turn out to be far more useful than it first appears.’

The exact design varies between vehicles, so not every center console will have the feature, and some slots may work better with certain phone sizes or cases. A particularly thick phone or bulky protective case may not fit securely between the supports. Still, when the dimensions are right, the slot can function as a surprisingly effective built-in phone stand without requiring an accessory or aftermarket holder.

What makes the feature so easy to miss is how naturally it blends into the surrounding cup-holder structure. Because the tabs look like ordinary pieces of molded plastic, many drivers assume they are simply there to separate or reinforce the cup holders. They may use the same material and finish as everything around them, making the actual purpose almost invisible unless someone happens to place a phone there.

So the next time you notice that strange little opening between two cup holders, try looking at it differently. It may not be wasted space or an unnecessary part of the console at all. It can be a cleverly integrated smartphone holder, designed to keep your phone upright while preserving the cup-holder space. It’s a perfect example of how car designers can hide useful functions in plain sight, leaving drivers to discover them years after they first bought the vehicle.
