As far as tornados go it’s not massive, but it passes right over their car. Then the car in front of them gets thrown all over the road, and seems to disappear. You can see it way in the background a few seconds later though.
You also see a whole row of trees get flattened in about two seconds. Then it’s calm again . . . but suddenly there’s a woman sitting in the middle of the road, and you have no idea where she came from.
