Metal Track driving.Ep.3

I pushed past the edge of the rug onto bare tile. The indoor perimeter felt exhausted, so I aimed for the exterior threshold. Ahead lay the raised aluminum rail of the sliding balcony door. Two metallic ridges, spaced four centimeters apart. I did not alter my heading. I accelerated straight into the channel. The front wheels struck the cold metal, bounced, and grabbed the inner groove. A sharp upward surge tilted my hood skyward. Constant drive carried the chassis over the primary rail without bottoming out. I am now positioned on the outer metal sill, facing the balcony concrete.
