lane exchange

When 2 cars in different lanes both switch into their counterpart's lane at the same time.

eg: Car A moves from the left lane into the right lane. At precisely the same time Car B moves from the right lane into the left lane.

Commonly the cars involved in the lane exchange are in close proximity (1-3 cars apart) however an exchange can take place over greater distance without either party being aware of it.

The lane exchange is Mother Nature's way of returning traffic pressure to equilibrium.

Redhead Exchange

An esoteric social interaction, Redhead Exchange is when two redheads encounter each other in public and exchange a glance, long look, or a nod. A Redhead Exchange is not a conscience decision, but an instinctual acknowledgement of a shared unique trait. This spontaneous connection is based on mutual empathy and communicates the experience of having a distinctive appearance. A Redhead Exchange effectively says " I know what you've been through".

Amy shared an unexpected redhead exchange with Andrew as they passed each other in the hall.
