Window rolldown tape trick - GIF

[metric_taper]

It's a fake video. You can see that the power window is being actuated by someone over in the driver seat, as the actor does not have the right mechanical movement to make it look like he's over driving what is a gear driven mechanism. There's no way he can overpower that. If this were a real emergency, he would break the rear window out to prevent glass shards from spraying the infant.
