Well let's see -- I'm 31 and have never owned a car or held a driving licence. However, I was dependent on the family car until I was 15. Then my parents separated, my father took the car, and I started doing the family shopping on my bike, which involved riding into the next town (I wasn't living in a city of half a million at that time). I'm fairly certain that puts me in the "over five years" category, and I'll leave everyone else to argue about whether or not it qualifies as 16 years or 31 years.
