Would you consider a brother who allows his sisters to travel alone with a non-mahram driver a red flag? It threw me off when I found out about it, even though the family is "religious," but this made me uneasy. His father passed away a long time ago, and the girls are more than the guys, with only 3 brothers, 2 working, one in the city I live in and another in the city her family lives in and one studying who also lives in the same city. I am pretty sure they could've managed a way to ensure their safety. I found out that previously, two of the sisters also travelled alone. It has made me consider what I would expect as a treatment from such a potential because I would not be able to trust him or feel safe knowing this, nor in such situations. Is this supposed to be a hard boundary? It scared me because this is something I would naturally expect, but having heard this, I realise not everyone has this as a basic condition like me, especially considering it is not Islamically allowed for a woman to travel alone.
