Thats the thing though,people just drive through flood water in a panic trying to "get home" instead of just turning around and going back to high ground and waiting for a couple of hours...Most people who have to be rescued have purposely driven into the water to begin with thinking they will make it across,and its not just the driver and passsengers who at risk,its also the blokes who have to rescue them.I live up in the bush,and I drive across a lot of river and creek crossings which are sometimes flooded,and if it looks a bit deep or fast flowing, I will walk through them first before attempting to drive through,Its just common sense.Mate,youve really gotta explain to your missus that she is very lucky to still be here, and that what she did, usually ends in disaster.A car can be replaced anytime,loved ones cant,people have to remember this,getting home or saving the car is not worth the risk.
