A Little Roll Forward

Beep-hum! My axles suddenly felt light and ready to go. I gave my round wheels a tiny push, and whoosh—I rolled forward all on my own! Right in front of me sat a neat red-and-white camper van and a blue police car, perfectly still. I gently nudged my front bumper toward the side of the quiet police car, testing the space between us. Rolling works, turning works, and I can move whenever I want!
