Act as a visionary concept artist with expertise in futuristic infrastructure and sustainable technology. Create a highly detailed, photorealistic image of a [solar-panel-covered highway] stretching into the horizon, embedded with [glowing blue energy grids] that power the road. The scene should feature a fleet of [sleek, autonomous vehicles] gliding seamlessly in perfect synchronization, their exteriors reflecting the neon-lit environment. The sky should be a dramatic twilight with hints of auroras, emphasizing the eco-friendly yet advanced nature of the setting. Include subtle details like holographic traffic signs, drone taxis in the distance, and pedestrians walking on elevated glass walkways. The composition should evoke a sense of harmony between technology and sustainability, with a cinematic wide-angle perspective.
