Saying "we should arrange these two buildings far enough apart so that people
have to cycle, because I don't like walking" is not compelling. Strive to arrange them close enough to walk (or wheelchair) because that maximises accessibility to the most people. If people can afford to - and want to - cycle on top of that base, no problem. But don't make cycling or driving or owning a Cessna the
default.
