I had never encountered an adult who didn’t until I met my sister-in-law. My brother had to teach her how to drive. She is from Chicago where there is ample public transportation. She used to say she didn’t need to drive, but when they moved to the north burbs that changed. Since then I have encountered two more through my son at college. His girlfriend and one of his room mates didn’t drive. His room mate is from Cleveland and I assume there is a lot of public transportation there. His GF is from nearby Columbus, Oh. but she claims to be a very poor driver and is trying to be ‘green’. Alas, she has poor William driving her all over the place. She gets pretty indignant when I point that out. My son asked me not to do that any more. His roomie has since not only gotten his license but works for an auto dealer. GF still won’t drive despite my son’s trying to teach her. I will probably buy a hideous beater and take her out to the field and let her driver around to help build her skills.
