I did read the article... I only saw one line, the last sentence of the articule which says "maybe if tesla bites". How does that make that a tesla topic, regarding sun visors, and why did you post it in the model 3 section?
I'd guess this would be technically feasible with the Model 3's interior camera, combined with face detection software.
Maybe because the Model 3 already has an interior camera, one that could possibly work with this new visor?
