I would say there are two distinct effects in that video. The stacking effect and the blown away effect. Notice they are never show together at the same time.

For the stacking effect you could use a scatter inside the shape of the car to make points where you copy magazines/boxes onto the points over time. Perhaps look into the divide sop instead of scatter for a more uniform vs random locations generator for the points.

For the blown away effect. Create a hollowed out version of the car geometry. Once again scatter points across the surface and use a copy or instance node to copy random paper/magazine source geometries onto the points. Make the entire setup a rigid body and then you can use a force of a fan or wind to blow the pages away.
