In order to maintain the visual image scale of a door-mounted mirror reflected in the glass of the more-distant fender-mounted unit, the mirror would have to be 'up-sized', increasing its frontal area, and cutting into savings afforded by being located in 'slower, ' 'cleaner' air.
In the off chance of a collision with a pedestrian / bicyclist, the fender-mounted unit might prove more hazardous.
I never hit anything with the '64 Ghia, and it's fender-mounted mirror was rock-solid once adjusted, although it's lack of any 'housing' certainly must have 'amplified' it's drag.
The 'solution' Subaru XT mirror aerodynamicists came up with ( and borrowed by Tesla, Jaguar, Aston Martin, etc. ) was simply to move the unit away from the door by at least 80mm.

The article about Japanese legal requirement said they are convex. More field of view, but objects appear smaller.

Peep mirrors are moved in the opposite direction, closer to the driver's eye.

What's worst is the Autobahn passing mirror.

Door mounted much better for aero. I would look pictures of WRC car mirrors and their positions. Closer to driver in cars length wise is also better as air moves slower. You also have better visibility backwards as the mirror is closer.

a pillar corner design like used in tesla needs that your hoodline is higher than the leg part and still it creates more drag and noise than the door mounted position.

For my audi a2 project I first plan to install audi a1 mirrors. After that install my own design with same fixing pattern.
