I wonder what makes people try this? Underestimated the depth, overestimated what their vehicle is capable of, just didn't appreciate the power the water has? It's a global phenomenon, the states even has specific laws regarding driving around barricades and into floodwater.

The Rufford lane ford is a great example of this.

And, when the rescue staff are on their way to get you, do not unexpectedly leap off the roof of your car into the water like this clown apparently did.

Is that some local knowledge? The article doesn't seem to mention this as far as I can tell. Just that he was on the roof when they arrived, then they pulled him out of the water.
