35 I have referred to the key issues which are raised in this appeal, to some of the evidence, and to the findings on those key issues. It is important to note, however, that the trial judge's reasons were detailed and comprehensive and dealt with many other matters as well. He reviewed the conditions of the road and the topography, the prevailing weather, the vehicles, and the progress of all the vehicles to the relevant area. He set out all of the evidence led by the parties in some detail. He gave detailed reasons why he was unable to accept the evidence of Mr Van Der Zaag's passenger, Mr Bouma. He reviewed the evidence and reached conclusions as to the position of Mr Cuthbertson on the roadway after the collision; the position of Mr Cuthbertson's motor bike after the collision; the damage or absence of damage to the respective vehicles; the statements made by Mr Van Der Zaag to various persons; the evidence of Mr Marshall, including the cross-examination relied upon on the appeal; the investigation conducted at the scene by Senior Constable Hawley; and evidence given concerning the injuries suffered by Mr Cuthbertson. He reviewed aspects of the relevant law, and he then made findings as to the critical issues, including those which are now relevant to this appeal and which I have set out in full.
