A vehicle's side view mirror is typically convex. Here's why:*Convex mirrors:*1. Provide a wider field of view, allowing drivers to see more of the surrounding area.2. Reduce blind spots, making it easier to detect other vehicles or pedestrians.3. Display objects as smaller and farther away, which helps judge distances.*Concave mirrors*, on the other hand, are not suitable for side view mirrors because they:1. Magnify objects, making them appear larger and closer than they are.2. Have a narrower field of view, potentially increasing blind spots.However, it's worth noting that some vehicles have an "aspheric" or "compound" mirror design, which combines elements of both convex and flat mirrors. These mirrors aim to provide a wider field of view while minimizing distortion.Remember, the passenger-side mirror is usually convex, while the driver-side mirror is often a flat or slightly convex mirror, depending on the vehicle's design and local regulations.
