# V2 Drift, Canyon Duel, And Drag

Section 106 defines Carbon and NFSU2 inspired drift scoring, drag scoring,
Canyon Duel structure, crew lead-follow choices, and open-world outrun drift.

## Drift Scoring

Per-drift score is angle degrees from forward, ideal line proximity, speed,
duration, and multiplier chain. The multiplier chain continues through linked
corners and resets on straighten or wall impact.

Drift handling assists are clutch-kick entry, handbrake drift, and Scandinavian
flick. Each input scheme can expose those assists while keeping the score
formula stable for ranked play.

## Drift Variants

Solo Drift Run is per-track score attack with leaderboard support. Drift Battle
is a 1v1 lead-follow drift mode where the lead car defines line and the follow
car scores matching line plus proximity. Drift Tag-Team is 2v2 with team
aggregate score.

NFSU2-style Outrun Drift starts from an open-world rival driver encounter. The
winner is decided by a per-second drift chain win threshold.

## Drag Scoring

Drag scoring grants a perfect-launch bonus when RPM is at peak power on green
light. Perfect-shift bonuses trigger at RPM peak, and a multi-shift chain bonus
rewards repeated clean shifts.

The drag-mode camera is a behind-the-car follow camera with shift light and
speedometer dominant on the HUD.

## Canyon Duel

Canyon Duel is a 1v1 cliff-edge race on a winding canyon sprint track. The
defender half scores per-second lead-time. The attacker half scores per-second
close-time. Per-half final score determines the winner, and falling off cliff is
an instant loss.

At launch, Canyon Duel has three canyon tracks: `Track.Canyon.AkaiPass`,
`Track.Canyon.ObservatoryRun`, and `Track.Canyon.CoastalCliff`. Each has
authored cliff drop, cinematic camera, dramatic music, and scoring HUD.

Casual mode supports per-half restart. Career mode uses Canyon Duel as the
Blacklist boss climax through Section 101.6 integration.

## Crew Lead-Follow

When chasing, the attacker may choose PIT or avoid based on player strategy. PIT
attempts have success rules and defender lead-loss consequences.

## Verification

`DriftCanyonDrag_V2_Contract.json`, `drift-canyon-drag.json`, the
`RaceModes.Module` automation spec, and `check-v2-drift-canyon-drag.py` validate
Section 106.
