This is sad news, city have to get rid of cars, and make public transport free if needed
Australia is more than cities.
Cities can make public transport free and congestion charges if they want to reduce usage of cars.
But there's a few things that make this trickier in Sydney, than, say, much of European cities:
* Sydney is too hot/UV to comfortably cycle between 9AM-5PM for at least 4 months of the year. Maybe tree-lined corridors could help that.
* Sydney is very hilly. It didn't have centuries of being flattened. This makes it challenging, even for experienced commuters. Ebikes could help.
* Sydney has low density: houses are big, detached, and thus spread apart. This makes relevant cycling distances further.
EVs are much more aligned with Sydney, at least for tackling the polluting issues with cars.
