If the new setting feels unfamiliar, give yourself time to understand it before relying on it in demanding traffic.
The NHTSA notes that blind spots can still exist even with improved mirror positioning. Drivers should continue checking over their shoulders before changing lanes.
Does This Mean the Traditional Method Is Completely Wrong?
Not necessarily.
This is where the discussion becomes more interesting.
Some drivers are taught to keep a small portion of their vehicle visible in each side mirror. That approach offers a familiar reference point and can be helpful during parking and maneuvering.
Other approaches emphasize angling the mirrors farther outward to reduce overlapping views and improve coverage of adjacent lanes.
The most appropriate arrangement can depend on the vehicle, the driver’s needs, and the situation.
For example, a driver who frequently parks in tight spaces may value seeing the curb or the side of the car. Someone who regularly drives on multilane highways may place greater emphasis on monitoring adjacent traffic.
