Exuse Me. It is a Mitzvah to stop and pick them up.
I go to yeshiva on Ditmas Ave. and East ninth. and i have to take the coney island bus (B68) to get from Ave J until Ditmas. I appreciate it very much when people stop and pick me up, instead of waiting for a bus. I don’t see any issues with it. I don’t flag down cars but i stand by the curb and if someone is nice enough to stop i am happy.
