I’m pretty sure a zipper merge is usually when two lanes merge into one, in that case it’s fine and normal when the actual merging happens at the end, with cars from each lane taking turns to become the final lane (like a zipper).
And I’m also pretty sure he means when there’s one exit lane that’s really backed up and somebody in the non-exiting lane next to it that’s not backed up drives right up to the last minute and merges in, thereby “cutting the line”.
Not the same thing IMO, although I am very frequently guilty of the latter!
- mindslight 5y agoIt's only wrong to "wait until the last second to merge" when that line is going extremely slowly or is fully stopped. Most of the time there is a line of cars moving along at 70% of the road speed before an exit, because there is some "leader of men" going slowly in preparation for the exit (or not!), with plenty of room in front of them. In this case you're helping everyone by passing that line and using the road capacity they're wasting.
