DRIFT/RS AI Judging: Every Run Measured. Every Point Explained.

Learning from every run. Judging every run better.

DRIFT/RS AI Judging reads every car twenty times a second, to the centimetre, and turns it into Line, Angle and Impact scores that get sharper with every lap it sees. It learns each course by itself, catches the mistakes a judge looks for, and shows exactly where every point came from.

It is the newest part of Drift.RS, the system that runs every Drift Kings International Series round. From the box on the car to the score on the screen, the whole system is in one film, and a real lap driven at Serres can be replayed in 3D, right in your browser.

Better for the organizer. Fairer for the driver. Clearer for the fans.

• Organizers. Fewer arguments: every call has its evidence. The same judging on every run, every round, all season. Your rules: your points, your briefing, your last word.
• Drivers and teams. Judged on what you did, measured to the centimetre. No mystery: a report shows where every point went. Practice that teaches: every lap recorded and scored.
• Fans. Understand the score: every score is explained. See what the judges see: 3D replays on your phone. Miss nothing: mistakes are flagged live on screen.

Rules give it the framework. Every lap makes it sharper.

DRIFT/RS AI Judging doesn't wait to be taught. Every run it measures becomes experience: it learns what a good angle, a fast initiation and a close chase look like on each course, draws its own ideal line from the cleanest runs, and remembers where the field brakes. The more it sees, the better it judges, all by itself.

• Measure. Centimetre-accurate, twenty times a second. Two antennas on every car give position and heading. From that come speed, the true drift angle, the throttle, and all four tyres against the mapped track limit.
• Learn. It teaches itself every course: targets, ideal line and braking map are learned automatically from the laps it has analysed, practice laps included. No hand-tuning between events.
• Analyse. Understeer, wheels off, a spin, a late initiation, a possible contact, a lead breaking pace, a possible pass: every case is detected automatically and flagged live on screen, the same way every time.
• Explain. A judge that shows its work. Every point traces back to a measurement, and every lap comes with its own report.

It is built on how drifting is actually judged: the Drift Kings rules and drivers' briefing, the Formula Drift judging regulations, the Drift Masters guidelines and FIA reference material.

All 100 points. Every one of them measured.

Line, Angle and Impact, split the way the Drift Kings rules and drivers' briefing split them. Impact is not a feeling here: it is rotation speed, entry speed, throttle and momentum, read from the same centimetre positions as everything else.

• Line, 40. Zones and clipping points, and Connection: how closely the car follows the ideal line this layout has learnt.
• Angle, 30. Average angle, peak angle and corrections.
• Impact, 30. Fluidity and Commitment.

The judges choose the weighting for the event. DRIFT/RS AI Judging can score the whole run, or sit beside your judges as an advisor while the final call stays theirs. Either way, every lap comes with its report: every point, and the reason behind it.

In tandem battles the chase is judged on closeness, consistency and how well it mimics the lead's line, angle and transitions. The two sides add up to a suggested winner, or One More Time.

It sees what a judge sometimes doesn't see. And flags it live.

Every case below is detected automatically from the telemetry and shown on the broadcast the moment it happens.

• Understeer. Straight for longer than the course's own learned transition time: flagged live.
• Possible contact, and who caused it. The body-to-body gap closes to nothing with a sudden drop in speed. It tells whether the chase closed in too fast or the lead braked hard.
• One wheel off, two wheels off. All four tyres are checked against the mapped track limit. It knows exactly which one went off and marks it on screen.
• Lead broke pace. The lead brakes hard mid-drift and the chase has to straighten to avoid it. The gap that opens there is not held against the chase.
• Possible pass. Side by side, both drifting, and the chase's nose gets ahead. That is measured along the racing line, so running alongside on the inside of a bend isn't mistaken for a pass.
• Incomplete runs. A late initiation, a spin or a car that stops is named on screen the moment it happens, and the judges can still count the run.
• Early throttle. After a transition or a decel zone, the chase is back on the throttle while the lead is still off it: the mark of an aggressive chase.
