Exhaust Fumes

Imagine yourself sitting on the side of a road.  Make it a familiar road - one that you drive down or walk across everyday.  The grass beneath you is still wet from the rain the night before, but it doesn't bother you.  You look up and glance to your left.  You can see the outline of a car, its shape growing larger and larger as it travels down the road, coming closer to you with every passing second.  Closer, closer, and its growth is reversed as your head almost automatically jerks to the right.  The car is now shrinking ever so quickly until you can no longer make out its existence.  For just an instant, maybe even shorter, this car was right in front of you.  And you didn't even realize it.  What did it sound like as this car was merely feet from your being?  The moment your head jerked from side to side.  Was there a noise?  Could you feel it?  The car was not approaching, nor was it retreating.  It was there.  Yet its speed was inevitable.  You could not grasp it in your hands and bottle it up.  But if the car were to stop, right in front of you, the noise would be known, the sight would be known, the meaning would be known.  Is this really what we want to know?
