From inside a vehicle, a street scene unfolds at an intersection. An ambulance, recognizable by its yellow and blue color scheme, proceeds through the intersection. A gray car follows, and behind them is a white van. A pedestrian wearing a backpack, shorts, and a pink shirt crosses the crosswalk in front of the camera vehicle. Trees line the street, and traffic lights hang above the road. The sky is overcast. The white van has the license plate 4339 WLR. The siren is on.
