Beleive me after observing drivers from various parts of the country.............Texas is by far better and more courteous drivers than most.The exceptions of course being Dallas,Houston and San Antonio(my firm belief here is most of the a$$holes are transplants).
Stupidest drivers........hands down goes to Louisiana, Mississippi and Alabama.
Least courteous drivers......my vote goes to Colorado(as a matter of fact most are out and out pricks).
