AI Video Prompt: Ocean Tunnel Highway

Create a continuous ultra-realistic cinematic underwater scene showing a futuristic transparent glass highway tunnel built deep beneath the ocean. A curved glass transportation tunnel extends into the distance while realistic vehicles smoothly drive inside the underwater road system. The camera performs a slow forward tracking movement through the deep blue ocean environment. Outside the tunnel, a natural marine ecosystem surrounds the structure. Coral formations remain fixed around the tunnel area while schools of small fish swim together above and around the glass structure. A sea turtle slowly swims near the lower-middle area, followed later by a large shark moving calmly through the water. Maintain realistic underwater physics, natural animal swimming behavior, accurate glass reflections, water refraction, floating particles, and cinematic blue ocean lighting. Keep the same tunnel architecture, same camera position, same marine creatures, same lighting, and same realistic documentary-style visual quality throughout the entire continuous shot. No cuts, no scene changes, no extra objects, no fantasy elements, no unrealistic movements.
