It was that individually plausible choices can become a collective traffic wave. https://mohsin-mahmud.github.io/blogs/teach-the-car.htmlhttps://mohsin-mahmud.github.io/blogs/teach-the-car.htmlFri, 28 Aug 2026 00:00:00 +0600RoG-DAgger turns an old driving-school truth into a post-training strategy: the dangerous lesson begins after the learner drifts away from the ideal route. https://mohsin-mahmud.github.io/blogs/the-empty-road.htmlhttps://mohsin-mahmud.github.io/blogs/the-empty-road.htmlFri, 21 Aug 2026 00:00:00 +0600No new transportation-specific LLM work cleared the evidence bar in this watch window. That quiet week is itself a useful signal about where the research pipeline remains thin. https://mohsin-mahmud.github.io/blogs/after-the-crash.htmlhttps://mohsin-mahmud.github.io/blogs/after-the-crash.htmlFri, 14 Aug 2026 00:00:00 +0600A week of research exposed the difference between noticing an anomaly and understanding a transport system well enough to act without punishing innocent behaviour.
