Smog

Head bobbing

Hands beating the steering wheel

Windows down

Singing like you do in the shower

Waitin' for the light to turn green

Watchin' the cross traffic 

Zoom zoom zoom

Air guitar solo

An eighteen-wheeler pushes through the intersection,

A widening gap in front of it

And a cramped line of cars behind it

As it moves sluggishly under all that weight,

While everyone stopped at the light watches with a frown.

Head bobbing

How embarrassing...

A thick, low cloud of smoke trails behind the truck,

Slowly creeping up to ruin the clean air,

Like some greasy, sleezy brown rat,

Slinking toward the open windows,

Sniffing around the wheels.

Air guitar

Push the button

Windows up

Disgusting...
