I have a feeling Dunn probably could have been in an ok condition to drive a car, he was just driving like a maniac, which is incredibly stupid after drinking. I bet, given his same blood alcohol content, if he wasnt a star of jackass and was driving a 4 door family sedan, Ryan Dunn nor anyone else would not be dead right now.
I know alot of people like to finger point and condemn anyone that drives under the influence. I am fucking hard pressed to believe anyone that drinks has never driven afterwards and unless you carry a breathalizer with you, I doubt you know what your blood alcohol is, and I think you would be rather surprised to find out how you actually feel at .09. (I know from experience, I never got a DUI but my buddy got one when we both drove home from the bar after drinking the same amount after work when we worked construction together in college, which was about 6 light beers over an hour, he blew a .1 and weighed more than i did, in that instance, even if pulled over with how I felt I never would have dreamed in a million years I would be over the legal limit, i did not feel intoxicated in the least).
