Watched American Graffitti again.....for the 200th time

There's a scene earlier when Harrison is talking to someone at a stoplight and you can see the steering column in the '55 move around with his movements.

You didn't sit on a stranger's car unless you were looking for trouble. You really didn't sit on a nice paint job. And only the naughty girls asked a stranger for a ride home. Back then, of course, they made it home...eventually...
