Have you thought about how people get to the grocery store or to an appointment when they can’t or should not drive themselves?
I think getting from here to there is too often taken for granted in the US currently. Transportation can be a bit challenging for people who have diminished mobility or decreased vision.
Driving a car spells INDEPENDENCE for most Americans in this day and age. Have you considered offering to run erands for an elderly neighbor or someone who doesn’t drive due to a disability?
