Turn M4p - Wrong

You don’t stop.

You try to reverse. The gear shift moves, but the car keeps going forward. The rearview mirror shows only more road behind you. More trees. More silence.

The sign doesn’t say M4P. It says M4 in faded white letters, then a crack in the metal, then a handwritten P in what might be rust or might be something else. Your GPS went quiet three miles ago. Not "recalculating"—just silent. The blue dot on the screen drifts across a grey rectangle where no map exists.
