I don't know how valuable it is if you've got no intention of driving. I passed when I was 17 or 18 and barely drove again until I was about 25 because I rarely had a need to - having the skill wasn't necessarily all that valuable in any quantifiable sense although I'm glad I passed when I was younger.
Perhaps you had no need to becuase you didnt have the means, if that makes sense. For example I cannot imagine going on holiday and not renting a car.
