Are you implying distracted driving is unique to only Tesla vehicles? The link you posted implies that, and then you immediately generalize your argument.
I intend to argue in the general sense. People will, in general, be distracted while driving. One protection is to simply be in a heavier vehicle so that you can survive more collisions when you're in a distracted state.
An alternative solution is "don't be distracted", but that doesn't seem to work in practice.
