We have to get to the destination by driving along a freeway we're not familiar with. I have an idea of the overall location and quickly can determine a good route as we approach some very complicated intersections and freeway exits. I know that some of the others can't probably do it as quickly, since they won't notice it. We get to the destination.

A bit later I am in the same situation -- again we have to drive to the same spot. This time I think the others will take the route, since I've now told them about it.
