I agree with this 100% - I am more concerned with teens and soccer moms on their phones, than I am with people exceeding the limit, and paying attention. I have done my share of spirited driving, but I was always 100% focused at the task at hand. The scum on their phones doing the speed limit is much more dangerous then those speeding, but focused on the road.
It's not a game of which-is-worse, both pose the potential to kill someone. You can be as focused as humanly possible and still it decreases your reaction time and stopping distance, as well as increasing the collision damage.
