Sense Sonnet - Tickler

Riddle Time Rhyme

A black cow is just standing there
In the middle of the road, when
'Round the corner a car does bear
At a fast speed and closing in
On the cow with no headlights on.
The makings of a tragedy
Are looming large to drop upon,
As a collision closer be.
But now just in the nick of time,
The driver sees the cow and breaks.
The question of this riddle rhyme -
How was the cow seen, for gosh sake?

The driver sees the cow - how now?
Becuz it is in daytime - wow!
