Being a heavy traveler for work, here's my driver "chart".
From worst to just bad:
Texas/mid-south drivers - Wreckless, never signal, heavy speeders, heavy cut-offs, DUIs everywhere
Maryland/Virginia drivers - Never signal, heavy speeders, heavy cut-offs, responsive assholes
Seattle drivers - Extremely indecisive, passive-aggressive
Ohio/Illinois/N midwest drivers - Wreckless, heavy cut-offs, occasionally racist (lol)
New York/NE drivers - Insanely wreckless, never signal (But decisive, at least)
California - Wreckless, heavy speeders (But are the most decisive)
That's all off the top of my head. I'd still have Florida, SLC and Phoenix areas but no time to type it out.
