Create a vibrant and nostalgic scene inspired by Arcade Fire's song "No Cars Go." The image should depict a fantastical, utopian landscape where no modern vehicles exist. Include a vast, open sky with shades of twilight, symbolizing the transition between day and night. A group of people, representing a diverse community, is on a journey through this landscape, moving away from a distant, silhouetted city. They are traveling on foot, by bicycle, and in other non-motorized ways, emphasizing the escape from modern technology. Incorporate elements like whimsical, glowing plants, and a serene, winding river, enhancing the magical and otherworldly feel. The overall atmosphere should be one of hope, adventure, and unity.
