Billy just grinned at the pose for casual cruising, and played Low Rider in his head as they joined the flow of traffic once more.
Having lived in California for some time, driven and driven by all manner of people, Billy didn't cling to the side of the car--but he also didn't particularly relish the ride. There was a particularly close call when someone crossed two lanes to move into theirs, and Billy saw bumper and headlights and quite physically twitched. Reaching out for distraction, he turned on the radio--popular rock.
Turning his attention to the front of the car and Vince, Billy very deliberately didn't look either way and waited until they arrived at the lot.
