When setting the driver's side view mirror using the contemporary (BGE) setting, what should the driver do?

When setting the driver's side view mirror using the contemporary (BGE) setting, the correct approach is to lean your head against the left-side window. This positioning allows the driver to set the side mirror to a point where they can minimize blind spots effectively. By doing this, the driver aligns the mirror so that, when looking to the side, they can see a clear picture of the lane next to them, while simultaneously keeping the rearview mirror adjusted to monitor traffic directly behind.

Leaning against the window helps ensure that the side mirror captures a wider portion of the area beside and behind the vehicle, creating a more comprehensive view of the surroundings. This method is specifically designed to enhance safety and improve the driver's awareness of other vehicles, especially when changing lanes or merging.
