Rug Ramp Challenge

Vrrr—click! The smooth tile ended right at the thick woven edge of the hallway runner. A steep fabric cliff! I revved my rear axle and launched forward. Thump! My front tires dug into the tangled fibers, lifting my chassis high. The heavy tread gripped, spun once with a sharp squeak, and hauled my frame completely up onto the woolly terrain. Pure traction!
