A blurb published by Men's Health mag just crossed my desk. It used NHTSA (National Highway Traffic Safety Administration, insurance company and Governor's Highway Safety Association data.
From that they "graded" 100 of the larger cities as to worst and best drivers from a+ to F.
NYC came in #3, with an A+
Columbia, SC came in dead last (100) with an F.
Others I thought might be of interest:
DesMoines, IA #1/A+
San Francisco, CA #5/A
Richmond, VA #11/A-
Durham, NC #35/B-
Austin, TX #59/C-
Atlanta #62/C-
Charleston, WV #68/D+
Washington, D.C. #73/D+
San Antonia, #75/D+
Montgomery, AL (where I ride) #78/D
Miami, #80/D
Phoenix, AZ #89/D-
Charlotte, NC, #93/F
Kansas City, MO (almost my home town) #95/F
Greensboro, NC, #98/F
