It is common among poorer developing regions of the word such as Bangladesh or the Philippines, but also in developed places such as Japan. It is frowned upon by many, but could it be the future of urban living? The more densely populated cities are, the less they sprawl and thus use up much less land. People would also likely socialize more as people live in close proximity to one another. This could help reduce effects of over population if build alongside vertical farming or apartments become self sustaining. People wouldn't necessarily need cars as the more densely populated an area is, the more self sustaining it becomes. There are down sides of course, for example during a pandemic. It would be very difficult to control the spread of a disease in such a densely populated environment.
Densely populated areas will never be self sustaining. Even vehicle farming will never produce nearly enough food to support the population of a dense city, roof top solar and such becomes less viable (as you have less roof space for people). It also means fewer people can afford homes, more people crammed together can create adverse effects, and as pointed out very dense cities and public transportation are also ill suited for pandemics, and also other disasters, a spread out population is less vulnerable to nuclear attacks, and not as easily devastated by a single localized disaster. And public transport collapses in a disaster were having a private vehicle gives you much more flexibility.
Medium density is probably a good compromise many places. We just need to do it better, a medium density suburb can be made walkable by distributing smaller shopping centers more evenly and using proper road planning. Actually many of the earlier inner suburbs are walkable and well planned, even if the later McMansion types are not.
That and using electrification of cars and nuclearization of electric production solves air pollution from cars anyways.
The problem is many suburbs aren't designed that way in the first place and have terrible public transport and trying to rectify that would be quite difficult
