Board notes 5 details

Layout: A blue car sits on a wide horizontal road, an upper vertical spur ends at that road, the post office stands across the lower grass, and a four-arrow remote controls the car.
Goal: Center and aim the car, rebuild the missing lower connection with the upper road spur, then drive to the post office.
Opening: Use the remote to place the car directly below the upper spur and turn it toward the bottom of the screen.
Danger Zone: The lower route is initially grass; driving down before relocating the road segment cannot reach the post office.
Mechanics: Directional controls move and orient the car, while the vertical road itself can be dragged from the unused upper branch into the missing lower branch.
