At 6:30 am on Thursday, June 25, 2026, the Delhi-Gurgaon Expressway was already thick with the heavy, high-speed transit of interstate commuters. Sarthak Mattoo, a 33-year-old event management professional, was riding his black Pulsar motorcycle along the highway. He was commuting from his home in DLF Phase 4, Gurugram, to an event assignment in Noida. He wore a premium, high-quality helmet bought for him by his father, who had extracted a solemn promise that he would never ride without it.
