You need to decide just how important having a driving licence would be to you. For example, when I lived on the edge of Sheffield, there were 17 buses per hour into the city centre within a 5 minute walk of where I lived. There were good evening and Sunday bus services too, together with buses running all night within a reasonable walking distance from my house. I just couldn't see any point in learning to drive while I lived there and using buses (plus occasional taxis when needed) was far, far cheaper than owning and running a car.
However when, at the age of 37, I moved down here to semi-rural East Anglia, I immediately started learning to drive because both my employment and leisure opportunities would have been severely restricted without the use a car.
So the question that you have to ask yourself is do you actually need a car?
