Mannequin Driving

I pulled up at the lights the other morning. The sky was finally blue and the sun was still quite low in the sky, shining in through side windows of the car. I looked in my rear view mirror.
Behind me was lowered black car. (I'm a girl, I don't need to remember makes and models.) A young guy with a cap was in the driver's seat. The shadow of his cap and the sun streaming in through his driver's door window cast his face in a warm light.
His head was tilted slightly to the side. His chin jutted out over his neck. He didn't move, he was completely still with no expression on his face. The light made his skin appear like smooth plastic. He looked like a shop window mannequin arranged in position.
As the lights changed the car driving mannequin followed me down the street towards the mall.
