19 The four-wheel drive turned into Central Avenue, Mount Lawley, and proceeded in an easterly direction. Central Avenue is a dual carriageway, which is straight and very well lit. The weather was fine. Mr Garden was travelling on the same road, in the same direction. Both he and the four-wheel drive being driven by the appellant, were in the left-hand lane, each with their headlights on. Mr Garden's motorcycle's tail-lights were operating. Without any sign of braking, deceleration or attempt on the part of the appellant to avoid a collision, the four-wheel drive effectively ran down Mr Garden's motorcycle from behind. The initial point of contact between the two vehicles was with the front bumper bar of the four-wheel drive, to the left of centre, with the rear tyre of the motorcycle. The motorcycle and its rider fell onto the road, and disappeared under the bumper of the four-wheel drive, becoming entangled between its front wheels. From the point of impact, the four-wheel drive travelled almost 250 m before coming to a rest on the footpath, on the wrong side of the road, having passed through an intersection. The motorcycle was locked onto the undercarriage of the four-wheel drive. Mr Garden's body had somehow been ejected from the left side of the vehicle, about 150 m from where the collision occurred.
