A long time ago, two Canadian computer scientists published a paper where they had written a 1-page Lisp program that got a passing grade on the British Columbia written driver's exam. It relied on the fact that in those days, all questions on the exam that started with “Must...” had the answer “yes”, questions starting with “May...” had the answer “no”, any question containing “pedestrian” was answered with “stop, the pedestrian has the right of way”, and a few others. “Immediately notify the Superintendent of Motor Vehicles” was the default answer. As I say, this program passed the exam, and the result was presented at a Canadian AI conference. They've changed the exam since then. By the way, when I did my exam (long before this experiment), the person in front of me failed.
