@BillRM,
No, that graph does not say "it all".
You seem to have forgotten, or failed to comprehend, all the info posted in this thread, numerous times, on the significantly impaired driving abilities that can be demonstrated at a BAC of .o8--in fact, alcohol in any amount, negatively affects the functioning of the central nervous system.
But you either fail to recognize impairment, or you try to discount or deny it, and even when you consider yourself impaired by one thing or another, you drive anyway. So you have no interest in either promoting or practicing responsible or safe driving.
Keep drinking, BillRM.
