With free electricity bring offered in the afternoon because of excess solar would be a great car for most peoples daily commute cheaper even than public transport as this is less than $6 per day over 10 years
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.
