As long as the product demands a user to be looking at the road(and intends to keep it like that for a while), there is no reason to spend time figuring out how to solve legal issues in case the user isn't responsible.
Toyota was found legally responsible for its unintended acceleration bug from the mid 2000s when "the driver should pay attention 100% of the time" wasn't even something you would think to say because there were exactly zero driver assist features.
