Here's what my parents did:
When I was 15, about to get my driver's license, my dad would regularly take the car out bright and early on a Saturday morning, purposefully crash it into the biggest snowbank he could find in the neighborhood, wake me up, and tell me to figure out how to dislodge it. He made me take a tire off the car and put it back on 3 times before I was allowed behind the wheel for the first time. Once, after picking my sister up from a school event, he pulled over in Hopkins (we lived in Eden Prairie), gave her some money, and told her to figure out the bus system. He left her there on the side of the road and drove home.
At the time, we thought he was a mean old poopy pants. Now, of course, my sister and I are among the most competent, confident, and self-assured people we know. I'm not easily thrown into a woe-is-me, I-don't-know-how-to-cope-with-this tizzy. And I'm pretty sure I could find my way out of just about any pickle.
So...more parents could try those tactics.
