That is so sad,it's one thing pushing it and coming unstuck,but if the law's arrested the driver and charged him with dangerous driving there must be witnesses, chances are he was overtaking and our poor friend has collided with him.If that's the case or some other reason I don't "feel for the old guy" at all,fuck him,some of these 4x4 drivers think they own the road.R.I.P. mate whoever you was.
