Every time you decide to delay a trip during rush-hour, because of rush-hour - that is an example of what you are describing.
As an example, in Bellevue, Washington - the evening rush hour starts (and is really bad) at 3pm - there are that many people leaving work progressively earlier that there is still a rush hour of people leaving work early to avoid the big rush-hour.
