The problem starts at about 1:25 into the video when the trucker steams past the few tentative cars waiting to cross a completely flooded section of this "floating" bridge. It all works out fine for the trucker, but the cars next to it get utterly, completely swamped. A Ford Focus driver nearly gets washed off the bridge completely.
Now your commute doesn't seem so bad, does it?
