This particular trip was 4 min by car because most of the distance was on an A road. It would be a lengthy walk.
I now live in a big city but when I walk to the office it's just before school starts, so I see that yeah at first I'm passing kids happily walking with parents but just outside the school it's a jam of idiots who "just quickly" are here to drop the child from a car. The contrast in a few weeks when school is closed will be dramatic, that street is dead, but I bet every one of those parents thinks of it as a "busy road, they ought to do something about that" while not remembering that it's busy because of them.
