Some of these issues are also safety issues. Being distracted is certainly obvious in a car, and massive fines and even criminal charges are now the result. But there are subtle things one must do in many jobs, just generically paying attention, which results in a save vs unsafe outcome. Boredom at work used to be filled with paying attention to ... work.
The garbage truck example I mentioned? I can think of a dozen safety issues. Safety for the employee, safety for someone walking by. Any accident could result in criminal charges for negligence, surely, but workplace safety rules are an issue too.
Soon, eventually, workplace safety rules will likely mandate "No phone at work, period"... at least for many professions. At least, that's how I see some of this resolving.
