A big problem I see emerging is linked to this issue but is more concerned with speed limits set too low and traffic over compensating.
Due to our ridiculous 2mph tolerance, it is actually the norm for people to drive 10-15mph UNDER the posted limit. Many people I have spoken with about this have admitted, when prompted, that due to the boredom of being forced to drive so slowly, their mind wanders and feel, in the case of several, it is a good opportunity to catch up on phone calls.
So, slow the traffic down to the point where they are so bored that they are easily distracted, even to the point of making phone calls to keep their brain active. Of course it's all to do with safety.

And when the accident rate increases we can fix that by further reducing speed limits and adding more cameras.
