> The largest increase is rural/suburban "local/collector" (low-speed) roads. This is almost certainly due to the epidemic of phone usage: not noticing cars slowing down for turns, stop signs, sharp turns, pedestrians. Maybe, but I see more speeding than I see phone use. I've noticed on the narrow and windy rural/suburban roads near me that some cars are going so fast that they have difficulty managing the turns and go into the oncoming lane. There is a reason the speed limit is 25 or 35mph - factoring in the width of the road, the curves, the driveways, and side streets, that is the safe traveling speed.
