Well the new Polestar solved the problem… by removing the rear window altogether and slapping a camera in its place.
Not joking, look it up!
Aside, IDK if the Polestar 4 is "the new Polestar".
The Polestar 2 is on the roads - I've seen them, and the 3 hasn't even shipped yet, now due in 2024: https://electrek.co/2023/05/11/polestar-delays-polestar-3-pr...
What does that make the 4? The one after the new one? The vapourware?
It's possible to get _better_ visibility from a camera than a mirror. e.g. good placement, adapting to low light.
