I only got my license at 17 because it was annoying to find carpools to the XC races on sunday mornings I had already worked my landscape business with the bike and trailer for years. So far though, every other job since college has required on-duty driving so yes it's an important thing to have even if biking to work.

My sis almost had to be forced to get her license right before going off to college. She didn't actually own a car(or really drive) until she graduated though.
