There is none. She got drunk voluntarily and drove her car in that condition. She is lucky she is not being charged with homicide by use of a vehicle.
"The memorable example of this is woman buys coffee spills coffee in lap sues because she wasn't told that the coffee was hot. Common sense says the coffee is hot unless you ordered it cold. Shouldn't be able to sue for that. And there are any number of examples."
The McDonald's coffee case is one of the least understood cases in American tort history. McDonald's ran a promotion which allowed people to have free/unlimited refills on their coffee. In order to keep costs down and limit the number of refills, they super-heated the coffee to a temperature which would cause serious burns if drank immediately. If this wasn't bad enough, the poured the coffee into traditional coffee cups. The problem here was that the cups were not rated for the temperature that McDonald's was heating their coffee to. The result - a person who ordered coffee (and was holding it inbetween their legs) had a cup melt on them and dump abnormally hot coffee all over them.
The person would have been seriously burned no matter how they were holding the cup, because it dissolved.
