I don't currently own a driver's license.
It isn't that I never have; those who knew me in high school know that I drove constantly: dates, work, and so forth. I simply... well... I got in an accident. Didn't pay my ticket for a couple years. I got that cleared up, but pulling the suspension from the driver's license and getting a new card costs well over $100. So I never bothered.
But now there might be a reason to reconsider:
