So I believe there's a tradeoff here. People drive to work all the time staring at their phones and only glancing up at the road every few seconds. They always have the option of turning the assist systems off and going back to distracted driving the old fashioned way. Obviously companies have no financial incentive to do this, but I posit that not making it impossible to use assist systems while completely distracted is actually a net benefit for road safety.
I'd rather have Honda Sense driving a car down the interstate by itself than some dude who's only looking up when the road curves.
