I feel there is a basic deign problem with auto-rikshaw. The driver takes turn as he wishes because he view is restricted both vertically and horizontally and being a narrow cabin in the front side, his perception of vehicle width is that of his cabin width and not that of passenger seat portion. If the autos are uniformly wide where the width of both driver seating area and passenger seat area are same, this perception problem will not exist. And there should two wheels in front also instead of single wheel and along with a steering instead of a handle to control directional movement will ensure safe driving.
