Failed on a Ford Taurus from the 1st year of their production. The hood dropped off after a foot and you could never really tell how far in front of you the bumper was. Bumped a car parallel parking.

Passed on a 1980 Mercedes 200. That's actually the car I learned on. Passenger seat had a squeek, so when I botched a shift I would hear it squeek as my dad silently judged me.

Motorcycle license was on a Harley Street 500. It was a loaner as a part of a training class that got me a license at the end. I had fallen off and hit my head earlier in the day, and knew that I had a mild concussion. Decided to take the test anyway because if I finished the class but failed the test I could retake the test in a week. Passed the test with only one ding for putting my foot down in a slow sharp turn. Aced the written, despite having to read the questions 2 or 3 times each. I was the last one out of the room except for a guy translating the test to another guy in spanish.
