While I 'take the lane'. I don't intentionally cause a situation of traffic backing up behind me. At the same time, if I am going the speed limit on a two-lane blacktop where passing is too dangerous, motorists' just have to wait. The traffic code here gives motorists' the right to pass over the double-yellow line if the motorist can see a good distance. But, If I am in the busy city center, that is a two-lane blacktop with on-street parking. So, There is no room to pass.
