If there is no speed limit then relative speed differentials will be much HIGHER because you'll have one guy trying to go 65 and another trying to hit 120. And relative speed doesn't matter after you've lost control and are crashing into fixed objects.
Also the suggestion that you can add all these lanes cheaply is incredibly ridiculous. If California couldn't build a HSR line what makes them think they could build a highway of the same distance?
