President Trump proposes suspending the federal gas tax, a move intended to provide consumer relief but raising concerns about infrastructure funding and increased national debt. Research suggests consumers may not fully benefit from the tax holiday, while the policy could exacerbate funding shortfalls for road maintenance and repairs.
Tesla achieved a coast-to-coast cannonball run using its Full Self-Driving (FSD) system without any human interventions, demonstrating significant progress in autonomous vehicle technology. While the milestone showcases rapid advancement in self-driving capabilities, broader commercial adoption will depend on proving consistent safety across diverse driving conditions and weather scenarios.
Researchers at the University of Minnesota developed an AI-powered CCTV analytics framework to measure the effectiveness of soft infrastructure interventions (temporary pedestrian refuges, curb extensions) on traffic safety. The study found speed reductions of 16-20% at both signalized and unsignalized intersections in Minneapolis, demonstrating that computer vision-based traffic analysis enables rapid, cost-effective evaluation of urban design policies.
Uber's stock declined 1.3% despite launching Europe's first commercial autonomous taxi service in Zagreb, Croatia, in partnership with Pony.ai and Verne. The market reaction suggests investor skepticism about the immediate impact of this milestone on Uber's business.
Researchers developed a novel framework using large language models (LLMs) to analyze electric vehicle taxi driver charging behavior by integrating psychological traits and environmental factors. The study demonstrates that LLMs can reliably simulate real-world charging decisions across multiple urban environments, providing insights for optimizing charging infrastructure and energy policy.
Venture capitalist Joe Lonsdale, a Boring Company investor, pitched Austin's mayor a $2.6 billion citywide tunnel system comprising 45 stations to be built by Elon Musk's Boring Company. The proposal would begin with a smaller-scale tunnel connecting properties owned by Lonsdale's associates, demonstrating how private capital and infrastructure ambitions intersect with urban transportation planning.
FedEx Freight (FDXF) begins trading on June 1 as an independent company following its spinoff from FedEx Corporation. The stock is trading when-issued at $185, with analysts projecting a potential valuation of $275 if it achieves comparable multiples to competitor Old Dominion Automotive Group.
Uber has partnered with hotel management system Mews to integrate its transportation services into 15,000 hotels globally, streamlining guest access to rides directly through hotel platforms. This integration addresses a common hospitality pain point by embedding mobility services into the hotel booking and stay experience.
