By Kevin J. Krizek, Professor of Environmental Design, University of Colorado Boulder Deadly traffic incidents have declined in most developed countries in recent years. But in the U.S. they are becoming more common. Deaths in motor vehicle crashes rose more than 33% from 2011 to 2021. Since 2010, pedestrian deaths nationwide have climbed a shocking 77%, compared with a 25% increase in all other types of traffic fatalities. Light trucks injure pedestrians more severely than passenger cars in crashes, and the size of cars and trucks sold in the U.S. continues to swell. Some current models, such as the...

By Kwong Ming (KM) Tse, Senior lecturer in Department of Mechanical Engineering and Product Design Engineering, Swinburne University of Technology If you ride a bike and want to cut your risk of traumatic head injury, you should wear a helmet. A major review of 40 different studies and 64,000 injured cyclists worldwide showed wearing a bicycle helmet reduces the risk of serious head injury by nearly 70%. But there is a bewildering array of designs out there. How do you know if yours is up to scratch or when it’s time to replace it? I am a head injury...

By Anjana Susarla, Professor of Information Systems, Michigan State University The Federal Trade Commission has launched an investigation of ChatGPT maker OpenAI for potential violations of consumer protection laws. The FTC sent the company a 20-page demand for information in the week of July 10, 2023. The move comes as European regulators have begun to take action, and Congress is working on legislation to regulate the artificial intelligence industry. The FTC has asked OpenAI to provide details of all complaints the company has received from users regarding “false, misleading, disparaging, or harmful” statements put out by OpenAI, and whether...

By Matthew Pittman, Assistant Professor of Advertising and Public Relations, University of Tennessee Twitter has swapped the fluffy bird that used to symbolize the social media platform for a spindly black X. Ditching the company’s well-known logo and changing its name to a letter often associated with danger, death and the unknown is only the latest user-aggravating step CEO Elon Musk has taken since he bought Twitter in October 2022 for US$44 billion. But it is the most visually jarring one. The reaction has mainly been a mix of ambivalence, ridicule and scorn. For the most part, longtime Twitter...

By Alexander N. Taylor, PhD Candidate in Economics, George Mason University Confederate monuments burst into public consciousness in 2015 when a shooting at a historically Black church in Charleston, South Carolina, instigated the first broad calls for their removal. The shooter intended to start a race war and had posed with Confederate imagery in photos posted online. Monument removal efforts grew in 2017 after a counterprotester was killed at the Unite the Right rally in Charlottesville, Virginia, where white supremacist groups defended the preservation of Confederate monuments. Removal movements saw widespread success in 2020 following George Floyd’s death at...

By Chris McCahill, Managing Director, State Smart Transportation Initiative, University of Wisconsin-Madison The U.S. has a car-centric culture that is inseparable from the way its communities are built. One striking example is the presence of parking lots and garages. Across the country, parking takes up an estimated 30% of space in cities. Nationwide, there are eight parking spots for every car. The dominance of parking has devastated once-vibrant downtowns by turning large areas into uninviting paved spaces that contribute to urban heating and stormwater runoff. It has driven up housing costs, since developers pass on the cost of providing...
