Create a realistic 15 to 20 second video demonstrating a proposed school bus safety device. Show a full-size American school bus traveling on a normal two-lane road. The bus slows down and stops to pick up children. Its red warning lights begin flashing. As the bus stops, show the existing school bus stop sign swinging outward from the side of the bus. At the same moment, show a new proposed safety barrier automatically deploying from the side of the bus. The barrier is mounted between the front and rear wheel wells and swings outward horizontally from the side of the bus, extending across the adjacent traffic lane. The barrier should be highly visible and positioned to physically prevent an approaching vehicle from passing the stopped school bus. Show a car approaching, stopping safely behind the extended barrier and remaining stopped. Show the children crossing safely while traffic is stopped. After the children have safely crossed, show the barrier retracting smoothly against the side of the bus and the stop sign retracting as the bus prepares to leave. Make the device look mechanically realistic and sturdy, with realistic hinges, mounting points, movement, and proportions. Do not show a crash, vehicle striking the barrier, or anyone being injured. This is a conceptual engineering demonstration only. Use realistic daylight, natural vehicle movement, accurate American school bus appearance, and believable camera angles. No narration or text is necessary.
