Car mirror setup in India: should bodywork stay visible, and when is a shoulder check essential?

Indian drivers are debating whether exterior mirrors should show a sliver of the car or be aimed farther outward to reduce blind zones. There is no single screenshot that fits every driver and vehicle: seat position, mirror curvature, body width and parking needs all change the useful view.

The practical test is whether a passing vehicle moves cleanly from the interior mirror to an exterior mirror and then into direct peripheral vision without disappearing for a dangerous interval. Blind-spot monitoring and convex add-ons are aids, not substitutes for observation and signalling.

Safe setup checklist

• Set the seat, steering wheel and normal driving posture first.
• Centre the interior mirror on the usable rear window.
• Adjust each exterior mirror to reduce unnecessary overlap while retaining only the spatial reference genuinely needed.
• Verify the hand-off with the car stationary and a helper outside, or in another safe controlled setting.
• Recheck after another driver changes the seat or mirrors.

Do you retain a sliver of the car for reference, or set the mirrors farther outward? What vehicle and seating position are involved, how do you verify that a passing two-wheeler never disappears between view zones, and when do you add a direct shoulder check before moving laterally?
