I read someplace ...that in ROman times.....there was this defense of being drunk...and they were not responsible for their actions...........but it was ruled invalid.....not sure what the real legal term was...but it translated into 'CRIME OF THE GRAPE'.....

If you render yourself  in such a condition as to lose control of yourself...law is unsympathetic  . 

As for this cabbie.........hope your citizenship is sound......cuz if it's not........good bye
