I saw a lady walking along the side of a rural road - this was about 12 years ago, so there weren't buses then, and there won't be in the next 12 years either - so I pulled over and asked her where she was going. Turns out she was going to walk, in the summer heat, to a grocery store about 10 miles away.

We shared my car just fine. But I certainly wouldn't go over to a neighbor and ask for a ride to the grocery store if my car was running ok.
