March 2026 is a landmark for autonomous driving worldwide. The United Nations Economic Commission for Europe (UNECE) Working Party on Automated/Autonomous and Connected Vehicles (GRVA) adopted a historic draft **Global Technical Regulation (GTR) on Automated Driving Systems (ADS)** in January 2026 (document ECE-TRANS-WP.29-GRVA-2026-02e). This draft, now under review for final adoption at the WP.29 session from **June 23–26, 2026**, establishes the first truly global framework for Level 3+ autonomy . If approved—as widely expected—it enters force immediately across 60+ countries (EU, UK, Japan, South Korea, Australia, and many others via UNECE's 1958/1998 Agreements). A cornerstone of the GTR is the requirement for **Minimal Risk Maneuvers (MRM)**—also termed "Mitigated Risk Condition" or "Minimum Risk Condition" in related docs. When the Automated Driving System (ADS) detects a severe failure, inability to continue the Dynamic Driving Task (DDT), or exits its O...
When Polyphony Digital released the first Gran Turismo in late 1997, it didn't just launch a racing game; it established a new digital hierarchy for the automotive world. Before the rigid "Groups" of modern sim-racing, the original title relied on a more organic, performance-based classification that mirrored real-world car culture and the booming Japanese tuning scene. This ecosystem, built on a groundbreaking physics engine, defined a generation of gearheads. The Core Divisions: Arcade Mode and the RM System The structure of car classes was fundamentally split between the immediate gratification of Arcade Mode and the deep progression of the Simulation Mode (GT Mode).Arcade Classes (A, B, and C): These provided an easy entry point. Class C featured entry-level Japanese hatchbacks like the Mazda Demio, where handling and momentum were key. Class B represented the "Golden Era" of 90s sports cars, including the Nissan Silvia and Subaru Impreza WRX. Class A was r...
