AITA for refusing to stop the car for my step sister and refusing to drive her back?’

A man (28M) agreed reluctantly to pick up his step-sister, Jane (29F), during a long car ride to their mom’s house. Throughout the 8-hour journey, Jane caused multiple delays by making excessive stop requests, complaining about feeling sick, and even debating with him and his girlfriend over topics like marriage.
He refused to stop one last time when they were just 30 minutes away, which upset Jane. Upon arrival, she exaggerated the story to their parents, saying he was cruel. Now, after her continued passive-aggressive comments, he has refused to drive her back, leaving her without a ride home.

Here’s how people reacted to the post:
Do you think he’s justified in not driving her back given her behavior, or should he have handled it differently? Was Jane being inconsiderate, or does she deserve some understanding? Share your thoughts in the comments!
She can rent a one way u haul truck and take herself back home.
I’d say drop her off at the nearest greyhound bus station, So she can grab a bus back home!!! No excuse to stop to pee on the bus , Because they have a toilet in the back. Let her be someone else’s problem…. 👋🏼👋🏼
NTA. If you’re parents want to take her side, then they can drive her home and then they can find out what you and your girlfriend were going through.
If Jane is so sensitive to traveling by car, she should find other means – train, bus, airplane or broom.
