I remember a time in my '61 MGA that I had a brake line fail. I had to drive about 20 miles to get home, ever so gently, using the parking brake for the last little bit of stopping for traffic lights, etc. I was grateful that my parents drilled me on that exact procedure as I was learning how to drive. They also taught me how to drive without a clutch, and I spent many hours in an empty parking lot, learning how to parallel park and perform other basic operations, all with a nearly-full and unsupported paper cup of water. Any spills triggered a reset of the exercise.
