I don’t find it strange at all. She’s an independent woman, not a child or an invalid who needs supervision.
“Ten minutes away” is 20 min round trip for someone picking her up, plus time to stop what one is doing, get ready, etc. and perhaps she was just being considerate of their time.
We don’t know what other tasks and responsibilities AG and TC have on weekends - maybe a child’s activities, errands, DIY - and even a lost 45 minutes on a Saturday afternoon can eat into a working person’s precious weekend. Why NOT take a quick Uber instead?
