This girl who I dated a few times and "helped out" once wants to go see a famous tourist site 3+ hours drive away. So I offer to take her, and tell her she can bring her girlfriend too.

When the time comes to all get in the car, she insists on sitting in the backseat with her girlfriend.

If this was a 10 minute or even 30 minute ride I would say it's a little bit fucked but so what. But a 3+ hour ride?! This isn't a taxi.

I told her to at least try sitting in the front seat for the start of the ride (with the passenger seat leaned back so she can still chat with her gf), or do half up in front and half in the backseat.

She said "no!", so I said, "no!", we're not going for a 3+ hour ride, but we can go to another tourist site nearby. We ended up going nowhere.

What would you have done (as the driver or the girl)?
