I HATE driving in London. (6). It took me 90 mins to do 12 miles on Friday afternoon, making my drive to Devon take far longer than it should have. The daft thing is, it was cheaper to do that than get the train. When I drive up north, I tend to go via blackwall, unless i'm leaving/coming back at a ridiculously unsocial hour. It's not the shortest, but any route planner/sat nav will tell you its the quickest.
