There are times when the woman is the driver. Most of the time, though, is it the man thrusting into the woman, and that makes him the driver. Sucks for you if the walker goes to the police even if you were both drunk, but at the end of the day it's illegal to drunk drive, it's not illegal to drunk walk
Public intoxication is only illegal in most states if paired with disruptive behavior. It is not illegal to simply walk around drunk. Even so, hitting someone with a car while drunk is a felony. Driving drunk multiple times is a felony even if you don't hit someone. Public intoxication is a misdemeanor
If you're in a vehicle, you have more ability to harm someone with that vehicle than an individual walk has to harm you while you're in the vehicle. In the case of Jane Doe, I would argue that being in a group (ie the group of frat guys) is equivalent to being in the vehicle and being an individual separate from the group (ie the one unaffiliated girl in the room) is equivalent to being an individual walking. So I would disagree that they were both drivers
This is objectively not true. If two people enthusiastically engage in sex, yet both are beyond the level of inebriation for legal consent at similar levels at the time of engagement, there’s no grounds for charges, which THERE IS CASE LAW COVERING, btw. So it does happen and has happened.
