There's something to be said too about the requirement by law of a minimum of parking lots per resident (that now outpaces housing per sq ft). This means even when the architects, residents, market and often councillors would prefer density, they can't and have to build islanded buildings even when denser:

In many parts of the world it operates a
maximum allowed per household, that's often below the US minimum. For example in my city it starts at one space allowed for a 3 bed property, and no need to allocate if not. Thus if it's a tower block of 2 beds, no need for
any parking, or for a business or skyscraper.
And don't forget almost all European urban areas were equally blighted in the postwar years by thinking car is king. Major cities recovering from razed centres rebuilt with a hard on for Courbousier -however, the urban planners were later
allowed to correct their mistakes, at profit.
