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."
It's also a failure of politics. If you tell people you're going to raise taxes to pay for the road, you're probably not getting elected. Toll roads ideally are just another form of tax that is more sneaky than straight up raising taxes.
People won't stop driving entirely. Some are legitimately afraid of rain, sun, wind, snow, etc . Placing the toll booths every 100m would go a long way to reducing traffic and reducing dangerous vehicle speeds.
