I don't think that having lane departure warnings would have saved that Honda. If I remember correctly, that incident another car was involved where they threw a cup at the Model S which tried to avoid it and ended up hitting the Honda. Now whether that happened or not I don't know but if true than 100% lane departure wouldn't have helped.
On top of that, according to studies by the IIHS lane departure warnings are useless. Actually, they found that lane departure warnings lead to more accidents.(Though it is within margin of error). But point being is that lane departure warnings don't do anything really.
The collision avoidance and adaptive headlights on the other hand would be a welcome addition.
