I had one of those unreported fender benders a couple weeks ago.
I was going north on 3 Notch, stopped in the left travel lane at Chancellors Run for the light.
When it turned green, I hesitated to let the cars ahead of me actually start rolling forward.
The young lady behind me spaced out and started moving before I did.
The jolt was definitely a wake-up.
We pulled into the left turn lane (leaving room ahead for those needing to turn).
Had a nice little conversation while she wrote down her info for me.
Inspected the cars, neither of us was hurt, I was comforting her, manure occureth and all that.
Bent my rear license plate and scuffed the bumper, which cleaned up with some Windex.
When I was a hunter's safety instructor back in Illinois, we'd get a copy of the state DNR Incident Report for the year.
Analysis showed most are caused by 3 factors: lack of knowledge, impatience, or inattention to what's going on around you.
They get worse when you combine 2 or more of these.
My wife and I are from western Massachusetts originally. Driving is a blood sport back there, but proportionately, I think they have fewer accidents than I see on a weekly basis around here.
