The driver's door opened, the car rocking slightly as he got in.
The car rocked away beneath the impact, teetered, and started to fall.
The car rocked, the man in the driver's seat made no movement.

The little car rocked as she slid across into the driver's seat.
The car rocked back and forth as the connection was made.
The car rocked as he squeezed back behind the wheel.
The car rocked with the continued yanking at the door handle.
The car had not rocked in the night; ergo, no wind.
It went very dark and the heavy car rocked gently in the damp wind.
