That last split decision when you decide you don't want to go through the tunnel or over the overpass or by pass the toll booth by jumping the concrete mediun strip at 100k's good thing your fourby has long travel in the suspension or otherwise your
wheels and diffs
will be left behind ~ or ~ overtaking that damned semi thats holding you up by
cutting the corner (left hand bend) and cutting through the truck stop on the side of the road to squeeze past, or overtaking
two vehicles travelling parrallel to each other by driving up the middle of them causing them to go offroad.
