What is in this image? Describe it as if you were explaining it to someone from the 15th century.

Behold, a scene depicting a large village with towering houses made of stone, each studded with countless small openings like the windows of a grand castle, but much higher and more numerous. There stands a curious cart unlike any horse-drawn vehicle seen before; it is a self-moving carriage without horses, adorned with a symbol of authority — a star, indicating it serves the village guards. This cart has shining bands atop, perhaps to signal and illuminate.There also stands a large figure, a man perhaps, with the attire of a village guard, though his cap and attire seem much tailored and uniform than what knights or protectors of yore might wear. His expression is one of bewilderment or confusion, perhaps a sign of some disturbance or mishap in the village square.Near the self-moving carriage, on the ground, lie scattered fragments, which might be remnants of a minor calamity, possibly caused by the carriage itself or some other unseen troublemaker in this busy village scene. Near this man and his cart also stands a tall pole bearing more curious markings, perhaps signals or messages using a system of colored lights—one lit and two unlit—likely a method for organizing the movement of these unique, horseless carts. Truly, this painted scroll shows marvels of a world far different from ours, a realm where craftsmanship and knowledge have mingled to create wonders and conveniences unfathomable to our humble minds.
