Just about every statement you made is wrong.  

" She was so inebriated she didn't know her address "
Not mentioned in the article.

"and the taxi was found by a cop a long way away from her home."
article says opposite direction with no mention of where she asked him to go.  Entirely possible that she gave consent and they found a nearby alley/side street.  Wouldn't be the first person to be horny enough to lower standards.

"When challenged he tried to hide her underwear."
Possible.  Even likely.  Proof?  The article infers that his stashing of the garments was taking place when the cop showed up, not that it was in reaction as you suggest.

"This is a woman so drunk she urinated in the cab!"
I know many people (both genders) who have done worse and subsequently consented and/or sought out sex.  

"Does anyone really believe she consented??"

Probably not.  But can anyone prove she didn't?  Convictions typically require evidence.
