In all, the sidewalk is carrying almost twice as many people as the roadway in less than half the space. And note that the roadway figures include the passengers on buses. Now, no doubt that's a severe case, but the pattern holds true elsewhere even if the magnitude is different. Even more damning in New York is that for most of the boroughs households without cars outnumber households with cars, in some areas by more than 50%. The median income for carless households is less than half that of those with cars, so it's no mystery which group has better access to influence planners ...
I wonder which parts of Adelaide we might find similar levels of skew? Perhaps King William St and Grenfell St, but maybe also Rundle St and Gouger St where the road/footpath ratio is probably close to 50/50 but the number of pedestrians must dwarf the number of drivers. And which of these would we be prepared to "correct"?
