a different pillar setup can allow for a more aerodynamic windshield, but such can block arguably considerable amount of visibility, which can be fixed by having a projector project a image of what it would look like if the pillar was didnt exist. this can be a selling point on more expensive trim of car even without these racecar pillars. the less glass also saves lot of weight but i wouldn't have too much glass replacement area just b/c too much artificial display might be annoying to the eyes by too much, for sell ability. also how about using primarily durable transparent plastic more befitting of taking impact in crash, then have minima actual glass for thermal insulation. i would exuse smaller heater unit in the name of the probable fact that people wont care to take off their winter clothing and turn of teh heater even more, especially not many electric car driver, its a safe bet.
this can also be used in single seater cars or liek this (rear seat probably should be rear facing https://www.aptera.us/forum/aptera-design-discussion/more-efficiency-and-midengine-sports-car-like-handling-feel-with-alternative-seating-position-for-4-seater ):
such can also be used to replace multiple screens with projected image friendly reflective material, and having the projector change its area of projecting images by tracking drivers eyes to locate where driver is looking at and project the image accordingly, or you multiple projector lenses that dont move, and project all displays at once like a normal multiscreen setup.
