The dartboard should be done for the London tube/rail network. It easy to get into central London from periphery (say Bromley to Victoria is 20min by train, 1hr by car), but periphery to periphery is not good if you dont have direct train (eg Bromley to Greenwich is 45min by train, but 20 min by car). The situation is worse if you are carrying luggage and/or kids.
