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.
So the RTA's own modelling showed the Rozelle Interchange would be a traffic disaster—but generating more toll road trips for Transurban was more important.
"The [NSW Roads and Traffic Authority] finalised the first business case for the WestConnex tunnel project in June 2013, with the help of road designers from around the world.
"[Paul Forward, a former CEO of the RTA] said the initial concept did not include the Rozelle Interchange.
...
"In 2014, an expert review group was formed to assess these plans.
"Mr Forward said it was at this point that TfNSW bureaucrats began to question the connectivity provided by the design.
"The RTA's former director of traffic Chris Ford told the inquiry that 15 alternative designs were modelled.
"Mr Ford said the modelling found that another motorway leading to the Anzac Bridge would cause congestion.
"'The issues that we see today were very clearly established in the modelling in 2014,' he said.
"In November 2015, after Mr Forward and Mr Ford were dismissed, TfNSW updated the WestConnex business case to include the tunnel to the Anzac Bridge, despite the congestion concerns raised by the modelling.
"In 2016, Transport for NSW updated the business case a second time ... creating a tunnel linking the Iron Cove Bridge to the Anzac Bridge."
...
"In 2018, the NSW government sold its 51 per cent stake in the Sydney Motorway Corporation, the body responsible for operating WestConnex, to Transurban for $9 billion.
"Mr Forward said the final design would generate a larger number of toll trips than previous options."

Same here in Stockholm. Now that the 21 km tunneled motorway ringroad is nearing completion they're adding several widenings of connecting motorways etc as separate projects even though even in the planning documents they're explicitly consequences of the big new motorway "bypass".
The decision to build freeways instead of rail in the post-war years, along with the low-rise single-zoned suburbs it promoted, has been an absolute planning disaster.
But the mistake can be fixed, and freeways can be removed.
City Beautiful's Dave Amos @citybeautiful has an interesting look at some of America's endangered freeways, and how communities can get them removed:
The saga of Waverley Park — Melbourne's car-dependent suburban AFL stadium with a planned seated capacity of over 150,000 (not a typo!)
A really good run down by @philip on the plans by the AFL (and its predecessor, the VFL) to build the world's largest stadium in outer-suburban Melbourne.
Unfortunately, a planned railway line past the stadium to Rowville was never built. That meant a massive 25,000-spot car park as the only real means to get there.
While most of it has been demolished and redeveloped for housing, the oval itself still used by Hawthorn Football Club as a training and administration centre.
@awelder@jedsetter@nictea@philip@fuck_cars You often hear from Melburnians that it's the world's most livable city, and how the CBD is laid out nicely in the Hoddle Grid is laid out compared to inner-city.
And how Melbourne's inner-suburban tram network means it has much better public transport than Sydney.
And it's true. Colonial Melbourne, funded by its gold rush, did a much better job at planning than early Sydney.
But after the World Wars, it's a very different story.
Sydney is at least constrained by Ku-ring-gai Chase National Park to the north, the Royal National Park to the south, and the Blue Mountains to the west.
That means the only places for new sprawl are either northwest past Rouse Hill, or southwest around Campbelltown and Camden.
As a result, there's a lot more pressure from developers to densify.
Meanwhile, Melbourne just has the Dandenong Ranges to the east and Port Phillip Bay to the south.
As a result, even right now, you have new housing estates past Pakenham, Melton, Wyndham Vale, and Craigieburn.
As for sprawling Australian capitals, I think Perth has definitely been punching above its weight since the 2000s mining boom.
There's now continuous McMansions sprawl right down the Coast from north of Joondalup to south of Mandurah.
And there's new subdivisions that are closer to Bunbury than they are to the Perth or Fremantle CBDs.
@ajsadauskas@awelder@jedsetter@nictea@philip@fuck_cars And Perth doesn't even have much of a pre-car inner-city, so it's dominated by car-friendly suburbia. The new train lines are good, but it's a pity they run between freeways and thus miss out on local walkable neighbourhoods around them.
So WestConnex was totally going to solve traffic in Sydney by adding more lanes for cars. Just a few teething problems on the Rozelle Interchange and it'll all clear up, they said.
I wonder how it's going?
"Gladesville and Drummoyne locals say gridlock is worsening in their suburbs following changes to improve traffic flow through the notorious Rozelle Interchange, with drivers using local streets as “rat runs” to dodge congestion."
Concerned about microplastics? Research shows one of the biggest sources is car tyres
A lot of the emphasis on reducing microplastics has focussed on things like plastic bags, clothing, and food packaging.
But there's a growing body of research that shows one of the biggest culprits by far is car tyres.
It's increasingly clear that we simply cannot solve the issue of microplastics in the environment while still using tyres — even with electric-powered cars.
"Tyre wear stands out as a major source of microplastic pollution. Globally, each person is responsible for around 1kg of microplastic pollution from tyre wear released into the environment on average each year – with even higher rates observed in developed nations.
"It is estimated that between 8% and 40% of these particles find their way into surface waters such as the sea, rivers and lakes through runoff from road surfaces, wastewater discharge or even through airborne transport.
"However, tyre wear microplastics have been largely overlooked as a microplastic pollutant. Their dark colour makes them difficult to detect, so these particles can’t be identified using the traditional spectroscopy methods used to identify other more colourful plastic polymers."
"Microplastic pollution has polluted the entire planet, from Arctic snow and Alpine soils to the deepest oceans. The particles can harbour toxic chemicals and harmful microbes and are known to harm some marine creatures. People are also known to consume them via food and water, and to breathe them, But the impact on human health is not yet known.
"“Roads are a very significant source of microplastics to remote areas, including the oceans,” said Andreas Stohl, from the Norwegian Institute for Air Research, who led the research. He said an average tyre loses 4kg during its lifetime. “It’s such a huge amount of plastic compared to, say, clothes,” whose fibres are commonly found in rivers, Stohl said. “You will not lose kilograms of plastic from your clothing.”"
"Microplastics are of increasing concern in the environment [1, 2]. Tire wear is estimated to be one of the largest sources of microplastics entering the aquatic environment [3,4,5,6,7]. The mechanical abrasion of car tires by the road surface forms tire wear particles (TWP) [8] and/or tire and road wear particles (TRWP), consisting of a complex mixture of rubber, with both embedded asphalt and minerals from the pavement [9]."
This is what America used to have, albeit with a much smaller population.
Lots of hubs, lots of lines crossing each other. Lots of small towns served in between.
See, what the people in America knew was that trains are faster than automobiles, and they still are.
So you've effectively turned one-hour straight train journeys (with one or two transfers at most) into two hours stuck in traffic.
Because unlike cars, the more people use trains, the more frequently services run, so it gets faster the more people use it. Whereas the more people drive, the more traffic there is, and the slower it gets.
I don't live near one of the big cities with traffic jams. There's generally only a couple cities per state (average) at most that commonly have traffic jams like that.
And yes, in the early 1900's. When a car was "fast" if it did 30 mph, had shit suspension, was good for about 60,000 total miles, had no freeways everywhere, and had like 3 million cars in existence. People didn't take the train because it was faster, so much as because people didn't own cars, and the ones that were available were only cars in the sense of they had 4 wheels and an engine attached. The trips taken back then by train were much slower than what a car can do today.
Looks like the Boring Company's Las Vegas tunnels are going about as well as you'd expect from an Elon project...
"The muck pooling in the tunnel at the north end of the Las Vegas Strip had the consistency of a milkshake and, in some places, sat at least two feet deep. ... At first, it merely felt damp. But in addition to the water, sand and silt—the natural byproducts of any dig—the workers understood that it was full of chemicals known as accelerants.
"The accelerants cure the grout that seals the tunnel’s concrete supports, helping the grout set properly and protecting the work against cracks and other deterioration. They also seriously burn exposed human skin. At the Encore dig site, such burns became almost routine, workers there told Nevada’s Occupational Safety and Health Administration. An investigation by the state OSHA, which Bloomberg Businessweek has obtained via a freedom of information request, describes workers being scarred permanently on their arms and legs. According to the investigation, at least one employee took a direct hit to the face. In an interview with Businessweek, one of the tunnel workers recalls the feeling of exposure to the chemicals: “You’d be like, ‘Why am I on fire?’”"
A rising road toll in the US. A rising road toll in Australia. Journalists give 1000 reasons why it could be happening.
And they studiously avoid mentioning the growing proportion of massive SUVs and pickup trucks on the roads. If they mention it at all, it's only in passing: https://youtu.be/Hb5_RUNeC0g?si=uuns6D1I6fGINdpU
But.
If you have larger and heavier cars, with larger blind spots, of course you're going to have more fatalities!
