I have driven in London precisely twice. I worked in Covent Garden for a while and got a company car with it. So my first drive was to get the car out of Central London and the second was to return it when I moved to another job.

Given the public transport systems in London, I would - personally - never choose to drive. To begin with, going a distance in London by tube is far faster. When I lived in Hatfield, for example, to get to Cecil Sharp House I would drive to and park at the end of the Underground line then travel in by public transport.
