Vehicle Mechanics & Driving Model

1. Driving Physics Model

Vehicles utilize a custom raycast / constraint chassis model on Roblox:

Tire Friction: Dynamic lateral friction curve allowing progressive grip breakaway into controlled drifts.
Weight Transfer: Visible pitch during hard acceleration/braking and roll during high-speed cornering.
Drivetrain Types:
- RWD (Rear-Wheel Drive): Oversteer bias; ideal for drifting and touge cornering.
- AWD (All-Wheel Drive): Superior launch grip and wet-weather stability; less drift angle.
- FWD (Front-Wheel Drive): Understeer tendency; easy for beginners to control at lower speeds.

2. Drift Mechanics

    C --> D[Throttle Modulation]
    D --> E[Corner Exit Straighten]

Initiation: Initiated via handbrake tap (Space on PC, handbrake button on mobile) or aggressive Scandinavian flick.
Angle Maintenance: Counter-steering angle paired with throttle level determines drift radius.
Multiplier Gauge: Maintaining a drift increments a temporary “Style Score” that rewards bonus Rep upon successful straighten-out.

3. Maintenance, Fuel & Damage

Mechanic	Implementation	Gameplay Impact
Fuel Tank	0–100% capacity; depletes based on RPM and distance driven	Requires occasional gas station stops; prevents infinite idle bots.
Collision Damage	Cosmetic panel deformation and slight top-speed penalty	Discourages reckless wall-riding; repaired at gas stations or garages for nominal cash.
Nitrous Boost (N2O)	Rechargeable boost tank unlocked via Tier 2 upgrades	Short acceleration burst with cooldown; tactical use for uphill climbs or speed traps.
