The video clearly shows a HUD lap timer, which was used to determine the lap start, end, and time for the displayed lap (Lap 7). The track name and vehicle brand/model were explicitly stated in the video title and description. The footage is continuous in-car POV. Driver skill was inferred from the description. The track length was estimated based on the lap time and observed speeds, and cross-referenced with a quick search for the track length (approx. 2.2 miles or 3540 meters, but given the speeds, a slightly higher estimate of 4500m was used for average speed calculation).
