That would definitely help save on costs on a lot of fronts but I’m sure you’d get people complaining about the cars lacking their own style/differentiation and everything being the same if they did that. It’d think it would still be cheaper for a screen though.

But doing that is how you save money yes. Same dashes between cars, seats, heat pumps etc. as many same parts as you can between as many models as you can with as few custom parts as you can, while still making a car people want to buy that differentiates itself enough.
