When Sydney is getting on the bus to leave for college, the US flag is on the bus by the door, but is displayed backwards, with the union (the stars) on the right instead of the left. It stays this way throughout the whole scene. When the US flag is displayed with the union on the right, it symbolizes forward motion. If the bus carried a real flag on a mast instead of just a sticker, the union would be on the right as the bus moved forward because the union side is attached to the mast.
