Why 'Five More Minutes' From the Navigation App Is Never Actually Five Minutes

The arrival time keeps moving, and drivers are convinced it's personal.

It's the sweetest lie in modern travel: the estimated arrival time. You leave with a confident number on the screen, text it to whoever's waiting, and watch it drift away like a mirage.

Five minutes becomes nine. Nine becomes fourteen. A crash two towns over adds twelve. Somehow you hit every red light in the county, and the app just quietly updates like nothing happened.

The engineering explanation is fair enough: the estimate assumes average conditions, and conditions are never average. But drivers have their own theory, which is that the app simply enjoys this.

Veteran commuters have adapted with a simple formula: take the estimate, add ten percent, and round up to the nearest excuse. Under-promise, over-deliver. The app could learn something.
