Leak Origin and Timing
The video, labeled Extended Leek, runs 24 minutes and 49 seconds and was posted after the leaker ran a poll seeking donations with an accompanying countdown timer. RockstarINTEL notes the leaker had been inactive for several weeks following the official Extended Look trailer.
First-Person Driving Footage

Several minutes focus on Jason driving vehicles from a first-person view, with the perspective remaining active after exiting a car. The footage looks unfinished, including missing reflections in wing mirrors, and RockstarINTEL stresses that first-person mode could still be cut before release.
Other Elements Shown
Additional scenes include a tank at a bridge and waterfall location seen in prior screenshots, in-depth vehicle customization, off-road racing in the first nine minutes, and brief story sequences that RockstarINTEL avoids detailing to prevent spoilers.
