Speeding More Slowly

My wife, Sari, was born with a lead foot. 

By all rights, she should have accumulated a bountiful harvest of speeding tickets over the course of her career.  But she understands how the system works. 

If she is, for example, buzzing along at 75 in 55 mile-an-hour zone and sees the state police ahead, she dons a sunny smile and gently taps on the brakes.  This action, of course, still leaves her well above the limit.  However, for some reason, the police seem to appreciate the gesture as a respectful acknowledgement of the majesty of the law.  Speeding more slowly is apparently regarded as akin to not speeding at all.
