Why are 15-minute cities so unpopular?

The idea of cities where everything you need on a daily basis can
be reached within a quarter of an hour by foot or bike has grown
in popularity in recent years, as local authorities adopt more
sustainable approaches to urban planning. In theory, by having
work, shopping, education, healthcare, and leisure all within a
short distance could reduce dependency on cars, improving
personal health and lowering carbon emissions. But the idea of
adapting cities in this way hasn’t been universally-welcomed.
