A camera mounted in a moving vehicle shows a view of a straight, paved road on a clear, sunny day. The road has two lanes in each direction, with white lines separating them. A sidewalk runs alongside the road, and trees line the sidewalk, with some having green leaves beginning to appear. Traffic signs, including pedestrian crossing signs and directional arrows, are suspended above the road. Cars are visible in both directions, and a few pedestrians are on the sidewalk. Streetlights line the road.
