That reminds me of when I was taken off car insurance without knowing it. On my father's car a few years back, both my brother and I were insured on it, but when my brother moved to Ontario, my dad took him off the car.
However I drove around for about a year or so without insurance and I didn't know, because for some foolish reason my brother and I were stuck in some stupid 2 for 1 deal or child deal, or whatever, and when my dad took him off the car, I was automatically pulled off as well without notification.
Good thing I'm the best driver in the world. *pokes*
