> but there are companies creating in-car cameras/sensors combined with machine learning to identify distracted driving of all sorts (not just phone use). some insurance companies will lower rates for less distracted driving, for example (not that this is a great solution either). while not perfect, I am actually a fan of this approach. in my ideal world, the government only administers sanctions to a citizen when they cause material harm to another person. let the insurance companies be on the hook (and possibly require the purchase of such insurance) for the actual penalties and have them calculate the risk. then excessively risky behaviors become de facto illegal because the insurance payments are not economic.
