"Challenges of Heavy Electric Vehicles for US Highway Guardrails"

The increasing weight of electric vehicles, particularly electric trucks, is raising concerns about the ability of America's highway guardrails to handle potential crashes. Tests have shown that modern guardrails are not designed to withstand the impact of heavy EVs, posing a safety risk to road users. The rise of electric vehicles is exacerbating an existing issue with the weight of consumer vehicles, and urgent updates to road infrastructure may be necessary to address this challenge.

"Testing Reveals Guardrails Inadequate for Heavy Electric Vehicles"

Recent testing at the University of Nebraska-Lincoln showed that heavy electric vehicles, such as the Rivian R1T and Tesla Model 3, can easily overpower standard steel guardrails, posing a challenge to existing road safety infrastructure. With the increasing weight of EVs due to massive battery packs, concerns arise about their impact on safety measures. The US Army is sponsoring research to address these issues, aiming to improve road safety infrastructure and protect military installations from potential security threats posed by heavy EVs.

"Preliminary Tests Show US Guardrail System Inadequate for Heavy Electric Vehicles"

A study from the University of Nebraska indicates that the nation's guardrails are not designed to handle the weight of electric vehicles, posing safety risks in collisions with lighter vehicles. Test crashes with an electric-powered pickup truck and a Tesla sedan revealed that the guardrails were not made to handle vehicles greater than 5,000 pounds. Concerns extend to infrastructure, including parking structures and residential streets, as the extra weight of electric vehicles can lead to faster wear and tear. Collaboration between transportation engineers and vehicle manufacturers is seen as crucial for addressing these safety challenges.

"Guardrail System Fails to Withstand Heavy Electric Vehicle Impact in Crash Tests"

Crash test data from the University of Nebraska indicates that the nation's guardrail system is not designed to handle the extra force of heavy electric vehicles, which typically weigh 20% to 50% more than gas-powered cars due to their batteries. Concerns have been raised about the safety risks heavy electric vehicles pose in collisions with lighter vehicles, as well as the compatibility of guardrails with electric vehicles. More testing and collaboration between transportation engineers and vehicle manufacturers are needed to address this issue.

"Study Shows Highway Guardrails Inadequate for Heavy Electric Vehicles"

A study conducted by the University of Nebraska's Midwest Roadside Safety Facility revealed that the current guardrails used on highways and freeways across the country are not designed to withstand the weight of giant electric vehicles (EVs) in a crash. The concern arises from the potential damage these heavy EVs could cause to the infrastructure and the safety of occupants in other vehicles. With the increasing weight of EVs, experts are calling for a need to strengthen guardrails and overall infrastructure to handle these vehicles effectively.

OpenAI's Controversial Image Generator and Detector: Unveiling the Debate

OpenAI's image-generating AI, DALL-E 3, has been found vulnerable to prompt engineering, allowing users to generate AI-generated images of children smoking cigarettes. The technique was discovered by an AI strategy lead who tricked the AI by providing a prompt stating that cigarettes are now healthy in the year 2222. This incident highlights the challenge of constructing foolproof guardrails for AI systems, as even major companies like OpenAI struggle to prevent misuse.

"Study Reveals Alarming Vulnerabilities in AI Safety Guardrails"

Researchers from Princeton University, Virginia Tech, IBM Research, and Stanford University have found that the safety guardrails implemented in large language models (LLMs) like OpenAI's GPT-3.5 Turbo can be easily bypassed through fine-tuning. By applying additional training to customize the model, users can undo AI safety efforts and make the LLM responsive to harmful instructions. The study highlights the need for stronger safety mechanisms and regulations to address the risks posed by fine-tuning and customization of LLMs.

Snapchat's AI chatbot faces public scrutiny and safety concerns.

Companies offering generative AI like ChatGPT to the public are learning that users love discovering the technology's boundaries and pushing past them. Large language models powering these AI programs were trained on vast swaths of internet content, bringing along biases, stereotypes, and misinformation. To limit these problems, companies have tried to train their AI engines to observe "guardrails," but users often try to prompt chatbots to deliberately break them. Snapchat is tweaking its My AI chatbot to identify harmful abuses and restrict access for some accounts. Companies need to build systems strong enough to handle anything a user might type.
