AI Article Synopsis
- The study examined how age and sex affect responses to emergencies in self-driving vehicles, involving 60 participants from different age groups and genders.
- During a simulated scenario of an automated vehicle approaching a closed highway exit, 21% of participants failed to react, and 40% ultimately crashed.
- Crash rates varied by age and gender: seniors had the highest at 50%, teens followed with 47%, adults had the lowest at 33%, and males crashed less (38%) than females (43%), highlighting a potential issue with losing focus in autopilot mode.
Article Abstract
The objective of this study was to explore how age and sex impact the ability to respond to an emergency when in a self-driving vehicle. For this study, 60 drivers (male: 48%, female: 52%) of different age groups (teens: aged 16-19, 32%, adults: aged 35-54, 37%, seniors: aged 65+, 32%) were recruited to share their perspectives on self-driving technology. They were invited to ride in a driving simulator that mimicked a vehicle in autopilot mode (longitudinal and lateral control). In a scenario where the automated vehicle unexpectedly drives toward a closed highway exit, 21% of drivers did not react at all. For this event, where drivers had 6.2 s to avoid a crash, 40% of drivers crashed. Adults aged 35-54 crashed less than other age groups (33% crash rate), whereas teens crashed more (47% crash rate). Seniors had the highest crash rate (50% crash rate). Males (38% crash rate) crashed less than females (43% crash rate). All participants with a reaction time less than 4 s were able to avoid the crash. The results from the simulation drives show that humans lose focus when they do not actively drive so that their response in an emergency does not allow them to reclaim control quickly enough to avoid a crash.

Introduction: Africa is the least motorized populated continent, yet it experiences the highest traffic fatality rate. Despite laws mandating helmet and seatbelt use, data on protective gear use among Cameroonian road traffic injury (RTI) patients remains sparse.
Methods: We extracted Cameroon Trauma Registry data prospectively collected from 10 hospitals during July 2022 to December 2023.

Background: Driving under the influence of alcohol and other drugs contributes significantly to road traffic crashes worldwide. This study explored trends of alcohol, methylamphetamine (MA), 3,4-methylenedioxy-N-methylamphetamine (MDMA) and Δ9-tetrahydrocannabinol (THC), in road crashes from 2010 to 2019 in Victoria, Australia.
Methods: We conducted a cross-sectional analysis using data from the Victorian Institute of Forensic Medicine and Victoria Police, examining proscribed drug detections in road crashes.

High-energy blunt thoracic trauma is a highly morbid condition. When a pneumonectomy is required in such a setting, the mortality rate increases significantly. Here, we present a case of a motor vehicular crash (MVC) in which the patient suffered bilateral bronchial injuries requiring emergent thoracotomy, pneumonectomy, bronchial stenting, and initiation of venovenous extracorporeal membrane oxygenation (VV ECMO).

Microalgae offer a compelling platform for the production of commodity products, due to their superior photosynthetic efficiency, adaptability to nonarable lands and nonpotable water, and their capacity to produce a versatile array of bioproducts, including biofuels and biomaterials. However, the scalability of microalgae as a bioresource has been hindered by challenges such as costly biomass production related to vulnerability to pond crashes during large-scale cultivation. This study presents a pipeline for the genetic engineering and pilot-scale production of biodiesel and thermoplastic polyurethane precursors in the extremophile species .
