As far as the DVD’s go, If the DVD’d didn’t show the mayhem and the adrenalin packed action who would buy or watch their rubbish dvd's
In the north we leave this to the main roads, local councils and national parks to control, if a track is to deemed too wet or dangerous the road is closed, signs are put in place, as the roads and tracks reopen maximum axle loads will be in place, as conditions improve restrictions are lifted.
My view - if the roads are open why not try, I have a serious financial investment in my vehicles and I know their capabilities, I weigh up my options, if the track or crossing is going to cause me problems in reaching my final destination, damaging the vehicle or injury to passengers then I will abort and find a more suitable way to proceed.
