That seems to be a mistake in a lot of "city of the future" concept art. All that empty space, tons of long strips of green and trees, very wide streets, huge squares everywhere, looks nice on a drawing or a render but is miserable to exist in because it means everything's really far apart and the scale of everything feels overwhelmingly. A lot of naïve attempts at a "green" city design have the same problem—in trying to incorporate all kinds of "eco friendly" green space they make an area less walkable, spread out the urban footprint, and make it a ton less eco-friendly.

It depends? Personally I like such large spaces, at least where I walked them in weather which allowed for that. Also E-bikes and rollers do exist now, not to forget old-fashioned bicycles.

Maybe "zone" them in ways which allows for many tiny oasis in the deserts of asphalt, concrete, steel and glass?

Everyone likes parks and plazas and the occasional wide boulevard, it's when there's a bunch of "green space" of indefinite purpose strewn about, and wide streets with big setbacks everywhere because they "look grand" and not to serve demonstrated human purpose. Utopian city designs and planned cities often suffer from both of those blights.

Like Brasilia:

High-rises but tons of wasted space. If they'd just put in a normal allocation of space for parks & plazas and right-sized roads the whole city could be much smaller and everyone would be fairly close to the actual countryside, not just unpleasant strips of green between wide roads.

Once you start looking for it in concept-art type city plans, it's everywhere: way too much purposeless, empty space, mostly in the form of non-park green spaces and too-wide streets and sidewalks. And if you have all those problems, in a real city at least, then you need a ton more parking, because nothing's walkable and the buses are slow (because everything's so far apart), and that's even more wasted space.
