From the judge's ruling: "She does not recall her argument with her best friend and that best friend's boyfriend ... somewhere between the hours of 12:15 a.m. and 12:30 a.m. on May 23, 2015." She got in the cab at 1:10, not immediately after.

In my view, it's just not clear why the judge would draw an inference about her state of mind from her being able to speak 40 or 55 minutes before entering the cab, but not draw any inference from her being passed out within 11 minutes of having entered it.
