Well, putting on my cycle training hat (a rather fetching mauve concoction) and offering unsolicited advice I would say that aiming for the advanced box is not always a good thing, filtering on the outside rather than the inside should be considered, reaching closer to the front rather than the front itself can be sufficient, that if you do not know how long the lights are going to stay green for then it is impossible to know if you can get to the front without ending up being squeezed out. Overall, being in the traffic stream rather than adjacent to it makes you more visible, more able to control and influence other road users behaviour and allows you to navigate junctions with more space.
