question:  Had the truck driver driving along Route 202 not noticed the change in road ahead while traveling, what would have likely happened?
context: Radio messages stated simply that Superior had seceded from Earth. A truck driver named Pierce Knaubloch was the first to report it. He had been highballing west along Route 202, making up for the time he'd spent over a second cup of coffee in a diner, when he screeched to a stop. He backed up two hundred feet, set out flares, then sped off to a telephone. Communicating by radiophone across the vast pit, they confirmed that the town undoubtedly was missing. A pilot who flew over it reported that it looked as if a great ice-cream scoop had bitten into the Ohio countryside. Someone pointed out that October 31 was Halloween and that midnight was the witching hour. A National Guard officer volunteered to take a jeep down into the pit, having found a spot that seemed navigable. The object loomed out of a cloudbank at twelve thousand feet and Studley changed course to avoid it. Don Cort had been dozing in what passed for the club car on the Buckeye Cannonball when the train braked to a stop. The redhead across the aisle in whom Don had taken a passing interest earlier in the evening asked, "Why did we stop?" Don hesitated, shrugged at the redhead, said, "Excuse me," and followed the conductor. About a dozen people were milling around the train as it sat in the dark, hissing steam. Don made his way up to the locomotive and found a bigger knot of people gathered in front of the cowcatcher. Don saw two men who must have been the engineer and the fireman talking to an old bearded gentleman wearing a civil defense helmet, a topcoat and riding boots. True, everything seemed to stop, and they could see stars shining low on the horizon where stars could not properly be expected to be seen. Don Cort and the fireman walked cautiously toward the edge while the professor ambled ahead with the familiarity of one who had been there before.
output:  He would have driven down into the pit where Superior was formerly located.
options:  He would have driven down into the pit where Superior was formerly located.  He would have passed right over the town and missed it totally.  He would have spilled his coffee while trying to make the sudden stop.  He would have floated above the ground and continued driving into the town of Superior.
