Ideally, some major cities want to have short buildings, narrow roads & highways and narrow bridges. Short trains, because of short stations.
W, D.C. has very short buildings, but wide streets and freeways and some wide bridges. The Washington Metro system has long trains, because the stations are also long.
SL City has short buildings, an intermediate size LRT system, but some wide sections of streets and freeways.
Honolulu, has short buildings and a short, but fast train. However, the H-1 is wider than 8 lanes in some sections.
San Diego has relatively short building, an intermediate size LRT, and some wide sections of freeways.
The Vancouver Trifecta
Over a century ago, Vancouver in Canada started to allow some buildings to be taller than most of the buildings in W, D.C. However, the streets are mostly quite narrow, as are most of the bridges one would expect for a major seaport city.
A strong case in point is the inadequate 3 lane Lions_Gate_Bridge. The LGB should have been adapted to become a bus and bike bridge several decades ago. Especially, if a parallel highway tunnel could have been built. It remains as the worst bottleneck-chokepoint in BC.
The YVR-Canada_Line wasn't designed to have 5 car trains, due to another case of the city not properly planning for the future. The stations are so short, that there is only enough level clearance to accommodate a 2.5 car train. Very small scale just like the LGB.
So far, no office tower in Vancouver has been permitted to have a 40th floor, but some residential towers have been allowed to be significantly taller.

https://en.wikipedia.org/wiki/First_Canadian_Place 72 floors in Toronto.
https://en.wikipedia.org/wiki/Columbia_Center 76 floors in Seattle.

That's the Vancouver Trifecta. Small scale or short buildings compared to most cities. Short trains compared to most cities & mostly narrow bridges.
Despite Vancouver having so many overlapping restrictions, the Greater_Vancouver region is the 3rd largest in Canada.
Despite the size of Canada, it has less than 1% of the worlds population.

In spite of a smaller population, Australia seems to function on a grander scale than Canada, in some ways.
