At least as a boy, a normal afternoon could turn into a full Fast and Furious spinoff mixed with everyone's favorite MTV show. A crossover if you will. One kid gets in the cart, one kid pushes, and nobody involved stops to consider that the cart is heading directly toward a wall, a parked car, or an innocent row of shopping carts. You would get launched, bounce off something hard, and stand up with one scraped elbow and the confidence of a pirate after a successful day of looting. You didn't have to worry about your body breaking OR anything in your pocket breaking.
Because phones were basically invincible back then. You could throw one across a room, drop it in a toilet or leave it outside in the rain, and it would still work. Maybe the battery cover came off, maybe the screen had a new little crack, but that thing would keep going. It had the durability of a set of keys and the repertoire of a brick.
