Well said. Personally, don't have experience with HUDs but at least Tesla seems to be willing to bring their A-game with regards of these things so there is hope. But like you said, I'd rather have a HUD that works 80% of the time as opposed to nothing at all (not counting the center-mounted display).
So you guys don't like the Model S? If you don't like the Model S, why would you buy a model 3? The model S has 2 beautiful screens.
