In one continuous four-second shot, the same beige vintage compact car switches on its lights, rolls from the wet shoulder into the near lane, and drives away along the forest-road curve. Use one stable, gentle pan only. Preserve the exact car body, beige paint, wheels, forest, road geometry, camera height, mist, and dawn lighting. Keep the movement physically plausible, with restrained tire spray and stable reflections, and settle cleanly into the final composition without morphing. Synchronized audio: one quiet engine start, tires on wet asphalt, light rain, and distant forest ambience. No cuts, no people, no extra vehicles, no readable text, no logos, no products, no advertising, no watermark.",
