There was a car, driving behind the cab, but it pulls off to a side street at the corner and parks, killing the lights. By the time the cab has gotten another blockbut is just idling at the stop sign (as if, maybe, waiting to see which direction the omega in front of the closed corner store goes) Bucky is just suddenly there, in the intersection, holding a hubcap.

The cab's backup lights come on.

Bucky throws the hubcap like a frisbee.

The sound of shattered safety glass is pretty loud, once the rear window is struck, but not as loud as the sound of the cab driver accelerating away.

Bucky still stands in the street. Takes a deep breath before crossing over to where Sam is standing. "Can I walk you home?" Seething. Agitated.
