Ultra-realistic cinematic first-person POV from inside a moving car, from the driver’s perspective, following a mountain bike descending an extremely steep and dangerously narrow mountain slope during heavy rain and light fog. The camera is positioned at eye level behind the rain-covered windshield. Subtle but constant shaking from rough terrain and unstable suspension. The muddy mountain road is dangerously slippery, carved into the edge of a massive cliff. On one side, a terrifying vertical drop disappears into dense fog. On the other side, sharp wet rocks and unstable ground. Heavy rain hits the windshield aggressively, droplets distorting visibility. Windshield wipers moving fast but struggling to clear the view. Water streaks reflecting dashboard lights. Occasional distant thunder and faint lightning illuminating the fog for a split second. The biker ahead suddenly loses partial control — rear wheel skids violently on wet gravel. The bike swerves dangerously toward the cliff edge. A near-fall moment: the back tire slides halfway over loose stones at the edge, small rocks tumbling into the abyss. The cyclist barely regains control at the last second. Inside the car, the driver instinctively slams the brakes — ABS vibration, slight fishtail skid on mud. The steering wheel shakes. Heart-pounding tension. Breath fogging slightly in the cold air. Ultra-realistic physics: tire friction loss, mud splashes hitting the windshield, suspension compression during braking, subtle dashboard vibration. Hyper-detailed wet textures: soaked rocks, muddy tire tracks, water droplets refracting light. Cold, desaturated color grading. High dynamic range. Cinematic depth of field. Natural motion blur. Micro camera movements reflecting nervous driving. Immersive sound design: heavy rain, wind howling across the mountain, gravel sliding, brakes screeching slightly, distant thunder, engine strain, heartbeat-like tension. Shot in 4K, photorealistic, raw documentary survival style, extremely intense and anxiety-inducing atmosphere.
