road safety

A one-minute UK road safety advert showing a family car crash in which an unbelted rear passenger kills his mother in a head-on collision. It is a notoriously graphic public information film.

Tom Scott explains why Ipley Cross in England's New Forest was one of Britain's most dangerous junctions. The angled crossroads lets a car's A-pillar hide approaching traffic and cyclists because there is no relative motion in the driver's view.

Not Just Bikes introduces the "stroad", a street-road hybrid common in the US and Canada that fails at both jobs. He contrasts it with Dutch design, where each road has a single purpose, and covers cost, danger and ugliness.

Not Just Bikes argues that oversized American fire trucks and fire department requirements push cities toward wide roads and dangerous street design. He compares this with the Dutch approach to emergency response.

John Oliver's Last Week Tonight segment on freight trains and railroads, covering how profit-driven practices undermine safety. It touches on longer trains and shrinking crews.

Not Just Bikes explains how North American speed limits are set and why posted limits matter far less than street design. It argues that drivers follow the road's cues, so safe speeds have to be built into the street.

Not Just Bikes explains why crossing streets is dangerous in the US and Canada, where roads are designed to move cars fast, and contrasts it with Dutch designs for pedestrians.

FortNine argues that e-bikes have injury rates and speeds closer to motorcycles than to pedal bikes. It argues riders should treat them with similar safety gear and caution.

Not Just Bikes explains why cars rarely crash into buildings in the Netherlands, attributing it to street design that forgives mistakes and to systematic crash investigation. It contrasts this with North American acceptance of such crashes.

A short documentary clip of Japanese railway workers and Toyota staff using pointing-and-calling, a safety practice of physically pointing at and naming things while working. It includes examples from several railway companies.

Not Just Bikes looks at the cancelled plan to spend over $200 million widening Wonderland Road, a stroad in his hometown of London, Ontario. He asks whether the cancellation marks a turning point away from car-dependent development.

Robert Miles introduces the first of several videos on the paper 'Concrete Problems in AI Safety', focusing on how AI systems can cause accidental negative side effects. It explains the problem in accessible terms.

FortNine looks at the data on why newer pickup trucks with tall, blunt grilles kill so many pedestrians, cyclists and motorcyclists. It argues that lowering hood height would substantially cut fatalities.

Not Just Bikes shows how traffic calming is built into streets across the Netherlands, from city centres to villages. Street design naturally slows cars and makes roads safer.

Chandler Carruth's CppNow 2023 talk describes Carbon as a successor language to C++ rather than a superset, focusing on C++ interop and a path to memory safety in large existing codebases. It explains why Carbon takes a different approach from Cpp2 and Circle.

A short Tesla promotional video touring the company's Crash Lab. It describes using data from the fleet and replicated real-world crash scenarios to engineer vehicle safety.

A Veritasium video, sponsored by Waymo, that rides in a fully driverless car in Chandler, Arizona and argues for putting autonomous vehicles on roads based on safety data.

A short Not Just Bikes video on continuous sidewalks in the Netherlands, where the sidewalk runs unbroken across side streets so cars must visibly cross pedestrian space. It places them within Dutch sustainable safety and Vision Zero efforts.

Practical Engineering explains how continuous welded rail copes with thermal expansion by restraining it, using the relationship between temperature, stress and strain. The video is part of a series on railways.

A short video of railroad workers in Storfors, Sweden, using thermite to weld rail sections together.

Robert Miles goes through ten common reasons people give for dismissing AI safety, adapted from Stuart Russell's list, and answers each one. It is aimed at skeptics and newcomers.

Aging Wheels compares a road trip in a Polestar 2 with an identical drive in a Tesla, showing the charging problems of non-Tesla EVs. It argues that outside Tesla's network, EV road trips have become frustrating.

A 56-minute fake BBC nuclear attack news broadcast originally made by Ben Marking, re-uploaded in full resolution. It is a fictional breaking-news special depicting nuclear war, and the uploader states it is not real.

Andrew Kelley's 2024 Zig roadmap talk, followed by a Q&A, covers the language's priorities and the state of the project. Topics include compilation speed, moving off LLVM toward a self-hosted toolchain, async, and the path to 1.0.

Andrew Kelley's roadmap talk on upcoming Zig compiler milestones, focused on compilation speed. It was given at a Zig community event in 2022.

A Last Week Tonight segment on food safety in the US. It looks at the FDA, the USDA and industry groups such as the Association for Dressings and Sauces, and how little enforcement there is.

Not Just Bikes explains how SUVs and light trucks have grown in size and share of US sales, and why that is dangerous for pedestrians, cyclists and city life. He covers the regulatory loopholes, such as fuel economy rules and the chicken tax, that favored them.

Copenhagen's bicycle ambassador Mikael Colville-Andersen argues in a TEDx talk that bicycle helmets threaten bicycle culture. He says they distract from road design and make cycling look dangerous.

Footage of a doubleheader of locomotives crawling over badly maintained track on a former Wabash Railroad line, now the ND&W Railway. The uploader explains the track had deferred maintenance for decades.

Robert Miles gives a remastered introduction to AI safety, adapted from a talk in London. It lays out why advanced AI could go wrong and answers common objections.

Robert Miles examines whether the case for AI safety is a Pascal's mugging, a tiny probability of an enormous payoff. He argues it is not, because AI risk does not depend on vanishingly small probabilities.

Road & Track puts a 2014 Porsche 911 Turbo through 50 back-to-back launch-control runs on a SoCal runway. The car completes 61 launches before the testers lose count.

The original Broadway cast performs 'The Internet Is For Porn' from the musical Avenue Q, with press-reel footage synced to the live performance.

A short silent video from the US Consumer Product Safety Commission warning consumers to stop using the Peloton Tread+. It shows a child being pulled under the treadmill, and it preceded Peloton's recall.

A motorcycle safety video on the SMIDSY (sorry mate, I didn't see you) accident, explaining the perception and optical illusion that makes drivers fail to see riders, and how riders can spot the signs and avoid it.

A woodworker shows how his table saw accident happened, why it happened and how to avoid a similar one. He describes severe hand lacerations from a blade contact.

Dave Jones of EEVblog debunks the Solar Roadways project, which raised millions through Indiegogo and government funding. He works through the solar generation and LED power calculations to show the idea isn't viable.

A Tesla Model S/X owner films his drive on US-101 in the lane where a fatal Model X Autopilot crash occurred, showing the car steering toward the lane divider without any warning.

Toyota's short promo clip showing a Mirai carbon-fiber hydrogen tank shot with a .50 caliber round at point blank range. The bullet pierces the tank, which does not burst, and the gas simply escapes and disperses.

Seattle landscape architect Fred Young gives an hour-long visual tour of Dutch cycling infrastructure, covering design details, continuous networks and how cycling fits daily life in the Netherlands.
