"Visualize a compact, fully autonomous urban vehicle designed for the bustling megacities of 2074. The exterior is a blend of glass and nanotech materials, allowing the car to change opacity for privacy or full transparency for an open driving experience. The car's shape is minimalistic yet futuristic, with smooth, rounded edges and a monolithic appearance. The doors slide upwards rather than outwards, optimized for space in tight environments. The vehicle’s electric charging ports are hidden within the sleek body, and the tires are composed of shape-shifting smart rubber, adjusting to various road surfaces for optimal performance. Exterior lighting is fully programmable, capable of displaying messages or patterns on the vehicle’s surface."--ar 16:9
