That's it? Quick count (for North America) yields 23 U.S. states (many, if not most, more than once), one Mexican state and four Canadian provinces. (Have also ridden in Italy for a total of about three weeks and Andalucia, Spain for seven weeks.)
During my September tour I rode through 5 states (VT, MA, NY, NJ and PA) alone. Courteousness of drivers can (and did) vary widely, even between different areas of a state. NY was definitely the worst. especially when you include the people with CT plates driving in NY. Rural/semis-rural MA is generally pretty good, but there is also a reason why MA drivers are often referred to as "M*******s." VT continues to be the best overall of those five.
Edit: I seem to forget WY & CO a lot. Total updated.
