The most frustrating thing about bicycle advocacy in Australia is that all the data is there, we've got in principle support from local councils and the state governments, and government plans for handling future traffic congestion and emissions reductions are relying on significant number (25%) of trips to be via active transport in a relatively short time frame (2030) but getting infrastructure to support these clearly stated goals is like squeezing water from a stone.
It's not a money problem or a logistics problem but only a problem of political will to do the things they need to do to meet the targets they've set.
