Another nasty accident right outside my apartment.

It was so loud I thought someone had dropped a huge item from the balcony.

3 people are injured, one seems to be critical. Police and ambulance are here. Don't feep like going down to look at what is happening. But I just can't understand how such accident can happen on a 50kmph road in a city right between 2 traffic lights.

I have seen more accidents on this road than I have seen in my entire life in all the places I have lived before.

Tor: Anonymisierungsdienst bringt Webtunnel gegen Zensur

Das anonymisierende Tor hat will mit Webtunneln Zensurmaßnahmen etwas entgegensetzen.

Die Entwickler des #Anonymisierungsdienstes #Tor (The Onion Router) haben eine neue Art von #Tor #Bridges eingeführt, sogenannte #Webtunnel. Damit sollen Nutzer sich auch von starken #Zensurmaßnahmen betroffenen Netzwerken aus ins Tor-Netzwerk und von da aus in alle Welt verbinden können.

Webtunnel sollen Zensurmaßnahmen umgehen, indem sie verschlüsselten #Web-Traffic (HTTPS) imitieren. In der Webtunnel-Ankündigung schreiben die Tor-Entwickler, dass die Nutzdatenverbindung dabei in Websocket-artige HTTPS-Verbindungen verpackt werden. Für Außenstehende sehe das genau aus wie eine HTTPS- respektive Websocket-Verbindung. Wer den #Traffic untersucht, sieht dadurch vermeintlich User ganz normal im #Web surfen.

It just struck me that the whole reason that induced demand always ends up at congested roads, is basic supply and demand: the less something costs, the more people will buy it. Demand grows until supply can't handle the demand and the price goes up. But a trip by car, when you already have a car and the road is already there, seems to cost nothing. Nothing, except time. So demand will go up, and the road will fill up, until the only meaningful personal cost, which is time, gets too high. And that happens when congestion slows your travel time to an unreasonable (frustrating and anger inducing) degree.

There are two possible solutions: one is to add another cost: make everything toll roads. The other is alternative modes of transportation, because then roads won't fill up until they're fully congested, they fill up until car travel time takes longer than the alternatives. Which happens way before congestion (if those alternatives are actually good and not themselves frustrating and anger inducing). And that's why even car travel in Netherland is so much better than in the US.

I knew this was the case of course, but now I really grok the economic logic behind it. And that's why more lanes on their own, without alternatives, can never solve congestion. It's a logical impossibility.

#Hertz is selling 20,000 used EVs due to high #repair costs

source: https://arstechnica.com/cars/2024/01/hertz-is-selling-20000-used-evs-due-to-high-repair-costs/

At the end of Q3 2023, Hertz told investors that significant price cutting during the year had "resulted in lower #EV residual values, increasing vehicle depreciation expense and negatively impacting salvage cost." Additionally, its rental EVs were damaged or crashed more often, and the much higher cost of repairs for #Tesla vehicles—on average about 20 percent higher than other EVs—has meant that Hertz's Teslas earn it less money per vehicle than its other rentals.

#Tire Wear a Major Source of #Microplastics, Say Researchers

Source: https://www.plasticstoday.com/medical/tire-wear-a-major-source-of-microplastics-say-researchers

Six million tonnes of tire wear particles are released globally each year. Particulate matter from tire wear is a significant source of microplastics in rivers and oceans, and tire wear in cities could pose up to a four-fold greater risk to the environment than other microplastics, according to the researchers.

Google's Project Green Light uses AI to change traffic lights to get a 30% decrease in red light stops.

"Green Light uses AI and Google Maps driving trends, with one of the strongest understandings of global road networks, to model traffic patterns and build intelligent recommendations for city traffic engineers to optimize traffic flow. Early numbers indicate a potential for up to 30% reduction in stops and 10% reduction in greenhouse gas emissions. By optimizing each intersection, and coordinating between adjacent intersections, we can create waves of green lights and help cities further reduce stop-and-go traffic. Green Light is now live in 70 intersections in 12 cities, 4 continents, from Haifa, Israel to Bangalore, India to Hamburg, Germany -- and in these intersections we are able to save fuel and lower emissions for up to 30M car rides monthly."

"Building on our decades-long effort to map cities across the world, we can infer existing traffic light parameters including: cycle length, transition time, green split (i.e. right-of-way time and order), coordination and sensor operation (actuation)."

"We create a model to understand how traffic flows through the intersection. This helps us understand typical traffic patterns including patterns of starting and stopping, average wait times at a traffic light, coordination between adjacent intersections (or lack thereof), and how traffic light plans change throughout the day."

"Using AI, we identify possible adjustments to traffic light timing. We share these adjustments as actionable recommendations with the city. The city's traffic engineers review the recommendations, approve them, and they can easily implement them in as little as 5 minutes, using the city's existing policies and tools."

'I was #kidnapped by my runaway electric #car'

He was also asked to hold the power button for a couple of seconds which also failed to stop it and the entire dashboard lit up with faults.

...

Police were forced to stop the runaway car by allowing it to slowly crash into their police van.

If you think why didn't he pull the handbrake, then you've never been in a modern electric car. Everything works via software, including the handbrake. There are no more mechanical controls. Since we all know how badly modern #software is developed and tested, as this example impressively shows, the #question remains why there is no #emergency switch that disconnects the #battery from the #engine?

lmost everyone in Europe is breathing toxic air

The Guardian

Guardian investigation finds 98% of Europeans breathing highly damaging polluted air linked to 400,000 deaths a year.

Europe is facing a “severe public health crisis”, with almost everyone across the continent living in areas with dangerous levels of air pollution. (...)

> Europe’s pollution divide: see how your area compares

(Text continues underneath the satellite picture.)

Satellite picture of Europe
Only 2% of Europeans breathe air within WHO guidelines for fine particulate pollution, with 30 million living in areas four times over those limits. Composite: Guardian Design/Getty Images.

reveals a dire picture of dirty air, with 98% of people living in areas with highly damaging fine particulate pollution that exceed World Health Organization guidelines. Almost two-thirds live in areas where air quality is more than double the WHO’s guidelines. (...)

Eastern Europe is significantly worse than western Europe, apart from Italy. (...)

Close to 30 million Europeans are living in areas with small particle concentrations that are at least four times the WHO guidelines. (...)

Traffic, industry, domestic heating and agriculture are the main sources of PM2.5 and the impact is often felt disproportionately by the poorest communities. (...)

But experts say urgent action needs taking now. They point to a growing body of evidence that shows air pollution affects almost every organ in the body and is linked to a huge range of health problems from heart and lung disease to cancer and diabetes, depression and mental illness to cognitive impairment and low birth weight.

One recent study found air pollution was responsible for 1 million stillbirths a year, another that young people living in cities already have billions of toxic air pollution particles in their hearts. (...)

resulted in hundreds of thousands of deaths each year.

“These deaths are preventable and the estimate does not include millions of cases of non-fatal diseases, years lived with disability, attributable hospitalisations, or health effects from other pollutants.” (...)

“This is the best data that there is available at the moment … Now we need politicians to be bold and ambitious and take the necessary urgent steps to tackle this crisis.”
