The dirty man's legs were all that showed from the place where he was working. Comstock leaned over Grundy's shoulders and said, "What about that key? It seems to be part of the works."
Shrugging, Grundy turned the key. There were a lot of things sticking up out of the floor and Comstock said, "They look like feet would fit on them, don't they?"
Sticking out one foot experimentally, Grundy said, "Hmmm ... yes, they do."
Then there was a series of explosions, and a sudden jolting start that threw Comstock into Helen's lap.
Later, when they had learned a bit about driving, they were all very grateful that the "car" had been pointed at the opening in the door when it started, for they knew that they would never have been able to figure out how to reverse it.
Their vehicle bucked and bounced as it roared out through the doorway. It was only after the first thirty seconds of movement that Grundy remembered that the other driver had held his hands on the wheel.
Trying this, he found that the car responded to his touch. Rather delighted, he turned the wheel sharply. Instantly Comstock was thrown off Helen's lap onto the floor of the "car". She landed on top of him driving the breath out of his lungs in a gasp that he momentarily feared was so noisy that The Grandfather, perched high in his tower, would hear.
But the sound of the explosions in the front of the car drowned out all other noises.
Careening down the esplanade away from the frightening buildings, away from the Fathers and The Grandfather, Comstock finally managed to push Helen off of him and get back into the seat. She was grinning excitedly and he found that he too shared in the feeling. In the front seat Grundy called back, "Hey, this is kind of fun!"
