The Evolution of Traffic

I sat at a stoplight waiting to turn left.
The "straight" lane was green.
But my left turn lane was red.
No traffic anywhere.
But I sat there
For nearly two minutes.
I'm obedient that way.
Time was
when this paved road was dirt.
When horseless carriages didn't have color-coded lights
Telling them what to do.
But there are a lot more horseless carriages now.
And a stretched definition
Of reasonably safe traffic patterns.
So we have the guidance
Of color-coded lights.
The more I think about it,
Maybe I'll just walk.
