The manner in which the accident occurred is fixed by the findings made in the local court. But upon those findings I do not think that the course which the plaintiff took should be considered to amount to contributory negligence on his part. The conclusion of the local court that not only did his conduct amount to contributory negligence but it constituted the "real cause" of the accident, I cannot follow. The expression "real cause" appears to imply that the admitted negligence of the defendant was not concurrent with the conduct regarded as negligence in the plaintiff. I do not understand how the plaintiff had a later opportunity than the defendant of avoiding a collision. The plaintiff was riding his motor cycle at a moderate speed along a main road. He was on his correct side and near the kerb. As he approached a side street on his left running into the main road at right angles, he saw the defendant's motor car going in the opposite direction. It too was travelling at a moderate speed, and on its correct side. A double tramway line ran down the centre of the main road and the car, which was driven by the defendant, was travelling with its off wheels on the tram rails on the car's left hand side of the road. The defendant held out his hand to indicate that he was about to make a right hand turn into the side street. The side street was a chain wide and had a road surface from kerb to kerb forty-two feet in width. Thirty-five yards has been fixed as the distance of the car from the centre line of this street at the moment when the defendant held out his hand to signal that he was about to turn into it. The plaintiff saw his hand out when the defendant still had some distance to travel before reaching the point round which he ought to have turned. The plaintiff not unnaturally maintained his course and speed. A second or two later when the plaintiff was about level with the fence alignment of the side street, that is, about thirty-three feet from its centre line, he saw the defendant change his direction and cross over the middle of the main road on to the other tram rails. The defendant's car was then about fifty feet from the centre line of the side street. The plaintiff continued his course down the main road across the mouth of the side street. He says that he had sounded his horn, and there is no finding that he did not. In going on, he acted on the assumption that the right of way was his and that there was ample time to cross before the defendant completed his turn. But, although the plaintiff did not know it, the defendant had not seen him. The road was clear and open. There was little traffic and none to obstruct the defendant's view. The hour was ten in the morning, and, though it had been drizzling, no rain was falling at the moment. The defendant was a man of seventy years of age who did not drive a car often. His failure to see the plaintiff was due perhaps to fluster more than inattention. But there was nothing to excuse it and there was no reason why the plaintiff should suppose that in broad daylight the evident fact that he was crossing the mouth of the side road should be unseen by the defendant who was about to turn into it. If the plaintiff had pulled up when he saw the defendant change his direction to make the turn his bicycle would have come to a standstill across the mouth of the side street. Exactly where he would have brought up his bicycle depends on estimation and is a matter of some uncertainty. The finding of the local court is to the effect that it would have stopped at least before it reached within eight or nine feet of the opposite kerb line of the side road. Perhaps it might have pulled up sooner, notwithstanding the wet surface. It follows that, if the defendant's car had taken any course which would have brought it into the side street, not on its wrong side of that street, but on its left hand or proper side, then by attempting to pull up his motor cycle, the plaintiff would have placed himself somewhere across the defendant's path. This would have been so whether the defendant came into the street diagonally or described a curve which, although not amounting to a proper turn, was not so flagrant a violation of the rules of the road, provided, of course, that he directed his car towards his left hand side of the mouth of the street he was entering. As it was, by keeping straight on as he did, the plaintiff would probably have passed safely in front of the defendant's car, if it had not been for a further mistake made by the defendant. In crossing over from the tram track on his proper side to that on the other side, the defendant was in fact beginning his intended turn. By continuing his turn, he had reached approximately a position where his front wheels had left the tram rails, when his daughter, who was sitting next to him, cried out a warning to him. Suddenly seeing the plaintiff, the defendant made the mistake of turning to the right instead of to the left. The result was an impact between his right hand mudguard and the plaintiff's motor cycle. The front wheels of the car were within three feet of the footpath of the main road. The car faced down the footpath of the side street, the kerb line of which was two feet further on than the left hand side of the car. This meant that, owing to the defendant's turn to his right, his car did not get as far as the corner of the two roadways, that the plaintiff did succeed in crossing the mouth of the side street in front of the defendant, and that the defendant struck him after he had done so, and even then with the right hand or further mudguard of the car. The finding is that, if the defendant had not turned to the right, his course would have taken him into the side street within three or four feet of its kerb line, that is, on the wrong side. It seems probable that in that event the plaintiff would have passed safely in front of him. Thus the defendant was cutting into a side street on its wrong side from a point on the crown of the main road thirty feet before the alignment of the kerb which formed the nearest side of the mouth of the street. And he was doing so without seeing the oncoming traffic. Even so, he would not have collided with the motor cycle but for his further mistake in turning to the right. It is quite certain that if he had turned to the left and opened a way to the plaintiff, no accident would have occurred. If he had not changed his course at all, the plaintiff would have just cleared him, that is, supposing that the other conditions were the same. The local court found that the defendant, when he did see the plaintiff, did not act negligently in turning to his right, and that he did not have an opportunity at this stage of avoiding the collision. On the other facts found, I think it is certain that a turn to the left, instead of to the right, would have avoided the collision and in that sense the defendant did have such an opportunity. But, of course, if what the defendant then did is judged independently of his previous conduct and if, on the assumption that for the emergency in which he found himself he was in no way to blame, the question is asked, was it negligent on his part to do the wrong thing at that moment, the answer may be that such a failure to rise to an occasion is not negligence. But allowing this, what I cannot see is why the plaintiff should be blamed for the accident.
