I've always been puzzled by the way so many people seem to think that the only reason anyone would travel anywhere other than in a car, whether that's walking, cycling, public transport, is because they don't have a car (or the car is out of action, or something).
I know people who will drive to the corner shop rather than walk, even though you could be there and back in less time than it takes to get in, adjust the mirrors, fasten seat belt, start up, drive and park. And they'll drive round the block multiple times just to park 2 or 3 paces closer to their destination.
I walk round the local shops almost every day - it's part of my exercise routine, I enjoy walking, and I'll do it even if we don't actually need anything. And no matter how many times I've explained to people that I enjoy walking and don't want a lift, the same people keep coming back with "You don't need to walk - I'll give you a lift", or winding down their windows when they pass me and offering me a lift.
They're being kind and considerate, but it just doesn't register with them that I choose to walk and that I never want a lift.
