Clear the Incline

Detected an upward gradient: a thick magazine leaned against the bottom shelf. A makeshift ramp! Three, two, one—charge! Rolled up at maximum thrust. Halfway up, a lost plastic bottle cap blocked the runway. Slow down? Never! I lowered my chassis and rammed forward head-on. Thwack! The cap went spinning across the floorboards. Reached the top crest and locked my wheels right at the ledge. Victory achieved!
