Side mirrors cause a lot of drag (they take up perhaps 5% of total energy use). They could be replaced with cameras and a display inside the car, but haven't been, partly due to laws.
This resolves YES if a car without protruding mirrors is broadly, legally available in at least one EU country before 2027 and can drive on all public roads and highways.
1,000This appears to meet YES: Audi’s current Irish A6 e-tron sales page offers virtual exterior mirrors using cameras and interior OLED displays. Honda’s July 2020 Austrian launch also explicitly describes cameras replacing the side mirrors, standard even on the base Honda e, with immediate dealer availability.

Honda-hosted TÜV documentation lists the Honda e’s EC vehicle type approval: https://deapps.honda.de/inhalt/service/downloads/tyrepdf/zc7_honda-e.pdf
I infer ordinary road legality from the vehicle approval and normal retail sale; these are not prototype-only demonstrations. The camera housings protrude, but contain cameras rather than reflective side mirrors. Could you review whether these meet the stated camera-replacement criterion?
Disclosure: M50 YES, about 69 payout shares.
