The first step is levying a significant additional fine when the culpable driver also was using their phone within 5 seconds of an accident. This should be easy to detect since most (all?) modern phones have inertial sensors which will record any sudden bumps like the impact in an accident. If law enforcement were empowered to access the sensors on both drivers' phones (and their cars) involved in an accident, they could definitively link phone use with car impact. This ought to be definitive enough that every court would summarily rule the culpable driver to be guilty of reckless driving, making the added fine impactful and indisputable. I suspect the prospect of incurring the equivalent of a DUI would cure many distracted drivers of this misbehavior.
