drivers will have a feeling, driving vision is always subject to the A-pillar or less occlusion. In general, the driver’s line of sight through the A-pillar, binocular overlap angle of 5-6 degrees, if the viewing angle from the driver, the overlap angle as small as possible, which means that for a narrower, thinner a-pillar. But in the eyes of the designer This is a contradictory issue, A pillar becomes small it will reduce its rigidity, safety will naturally be greatly reduced. But with the development of science and technology, we began to have a lot to resolve this contradiction programs, such as the installation of cameras in the A-pillar to make it to achieve the effect of perspective.
