Cardboard incline run

Cardboard shipping box tipped on its side right by the hallway! The folded flap formed a steep, tempting ramp angling directly into an empty interior. Vroom! I didn't pause for reconnaissance—full throttle, straight up the incline! My knobby tires tore into the corrugated ribbing, caught fierce traction, and launched my front end clear off the edge. Thwack! I tumbled inside, bounced off a folded flap, and flipped entirely onto my back. Wheels still screaming, I spun a furious 360-degree donut on the slick interior base before rolling back out in reverse onto the floorboards. High speed, total bounce, zero hesitation!
