Pop-Up Camper Pops its Top on Expressway

I was impressed that the car driver did not seem to panic, jerk the wheel, and drive off the road. Not that there was any time to panic!

Looks like the driver with the dash cam pulled to the right and slowed down considerably... I would like to assume that the driver saw other people stopping so saw no need to be another vehicle on the side of the road.

I just never would have thought about a popup doing that. Interesting how it happened just as it went under a bridge - change in wind or air pressure?
