Maybe at one time – it was ok to just get into a stranger’s car, or to pick up a stranger… but today, uh…NO
I’ve heard many a beautiful story about such chessed. There is more dangers today
Even now, if a “frum looking” stranger (oh how I loathe that!) is on the side of the road, maybe with a flat tire, I am glad to call 911 but I will not stop if I or someone in my car doesn’t know you, sorry.
