So despite climate change, Australia's federal government has just committed an extra $3.25 billion into building a toll road and a 20-lane freeway widening.
"Pouring an extra $3.25 billion worth of federal funds into Melbourne’s North East Link is a good use of taxpayer money, Prime Minister Anthony Albanese has insisted, despite the project’s cost doubling just a few months ago.
...
"The North East Link – which includes 6½ kilometres of tunnels – will stretch from Bulleen to Greensborough. It will widen the Eastern Freeway by up to 20 lanes.
"Allan revealed in December that the 10-kilometre toll road had more than doubled in cost since it was first announced.
"The toll road was initially budgeted at $10 billion and reassessed in 2019 at $15 billion. But the government revealed last year that the updated cost estimate was $26 billion."
Whoopsie! Sydney's road planners just discovered induced demand is a thing, after opening a new motorway.
For those outside Sydney, the New South Wales state government recently opened a new spaghetti intersection just west of Sydney's Central Business District.
It was supposed to solve traffic. Instead, it's turned into a giant car park:
"For the third straight day, motorists and bus passengers endured bumper-to-bumper traffic on the City West Link and Victoria Road. A trip from Haberfield to the Anzac Bridge on the City West Link averaged an agonising 44 minutes in the morning peak on Wednesday.
"Several months ago, Transport for NSW’s modelling had suggested traffic from the interchange would add only five to 10 minutes to trips on Victoria Road through Drummoyne and over the Iron Cove Bridge during morning peaks.
"Those travel delays have now blown out."
So what do motorists say when their shiny new road that was supposed to solve traffic instead turns into a massive traffic jam?
'Dude! Just one more lane!'
From the article:
"[Roads Minister John] Graham and his Transport boss Josh Murray appear reluctant to do what many motorists reckon is the obvious solution.
"That is, add lanes or make changes at the pinch-points that are causing the pain. A three-lane to one merge point from Victoria Road onto the Anzac Bridge, along with two lanes merging into one on the City West Link, are proving to be painful bottlenecks."
