When I got my license back in 1980, Iowa would set up a course in a parking lot with cones for slalom, keyhole, etc. sections. Most people had someone bring in a little Trail 70 Honda automatic to take the test. I, of course, couldn't follow convention and rode my F1 in to take the test.
Failed the first time when I bumped a cone on the slalom section with my foot. Came back the next week and passed the slalom, but had to put my foot down in the keyhole section. The instructor looked at me and said, "You're going to keep coming back until you pass with that bike, aren't you?" When I answered in the affirmative, he signed off that I passed and I got my license. Nice guy.
Should have gotten the course dimensions and practiced back then, young and dumb....
