Who cares?
There are standard rules for this stuff in a courtroom. I realize this isn't a courtroom, but we should want the same principles followed.
We almost 100% reject hearsay in a courtroom. The principle behind that is sound. We know eyewitness testimony is frequently unreliable. We know relayed information is almost always diluted factually. So for a witness testifying to what she was told, our default position should be extreme skepticism.
We don't have to have emotional discussions. We don't need it to turn into "OMG you are accusing this poor girl of lying."
I have zero issues taking her first hand accounts with a heavy weight and rejecting any games of telephone. I don't need to focus on her as a person or get into any discussions about misogyny, sexism, favoritism, etc.
Now if the driver of the vehicle was refusing to cooperate or the other passenger(s), I might change my mind. Because in that scenario the first hand account is not available.
But if the driver is willing and is not presented, the only motivations in question should be that of the committee, not this young lady.
