That one driver who drives just a little bit slower than the drivers ahead of and behind him or her that provides you the opportunity to bypass a long line of traffic to get in the lane you need, kind of like a shortcut. It's similar to how a lion will search a pack of gazelles to find the "weak" link to take advantage.
Instead of waiting in the busy lane for a mile, I drove alongside it and found my gazelle three-quarters of the way down. I cut my drive time by a few minutes.
