vehicle
Force-based wheeled vehicle: suspension, combined-slip tyres, engine/clutch/gears/differential, damage and cameras. New vehicles use this; existing recordings without it keep their legacy motor. Numeric zero uses the named preset.

Fields 30
| Field | Type | Unit / range | What it does |
|---|---|---|---|
preset | text | — | sports, sedan, suv, pickup, truck, kart or motorbike. |
mass | number | kg, 0 … 20000 | Mass override; zero uses preset. |
power | number | 0.1 … 4 | Engine torque/power multiplier. |
grip | number | 0.1 … 3 | Tyre friction multiplier; does not change surface identity. |
spring | number | N/m, 0 … 500000 | Spring stiffness per wheel; zero uses preset. |
damper | number | Ns/m, 0 … 100000 | Suspension damper per wheel. |
travel | number | m, 0 … 1.5 | Suspension compression travel; must exceed static sag. |
anti_roll | number | N/m, 0 … 200000 | Anti-roll bar stiffness; zero uses preset. |
wheelbase | number | m, 0 … 8 | Axle spacing override. |
track | number | m, 0 … 4 | Track width override. |
wheel_radius | number | m, 0 … 1.2 | Rolling radius override. |
wheel_radius_rear | number | m, 0 … 1.2 | Rear axle's rolling radius when it differs from the front; zero: the same. |
cg_height | number | m, 0 … 2.5 | Centre of mass above the model's ground pivot. |
simulation | number | 0 … 1 | 0 forgiving speed-sensitive steering, 1 direct simulation; never inflates grip. |
abs | true / false | — | Anti-lock braking; independent of the feel slider. |
traction_control | true / false | — | Cuts engine torque during driven-wheel slip. |
stability_control | true / false | — | Selective braking against excess yaw. |
automatic | true / false | — | Automatic gearbox; off enables manual shifts. |
balance_assist | true / false | — | Motorbike balance assistance; off permits falling over. |
drive | text | — | preset, front, rear, all. |
differential | text | — | preset, open, lsd, locked. |
camera | text | — | chase, bumper, hood, cockpit, replay. V cycles while driving. |
driver | text | — | racing or traffic on an ai_driver. |
lane_offset | number | m, -8 … 8 | Traffic offset from road centre, in its travel direction. |
speed_limit | number | km/h, 5 … 200 | Traffic driver's maximum speed (a racing driver's pace is skill). |
rubber_band | number | 0 … 1 | Optional racing speed adjustment; zero off. Never moves cars by teleport. |
skill | number | 0 … 1 | Racing driver's pace: 0.3 an easy rival (about 70% of its car's top speed, gentle corners) ... 1 flat out on the limit; 0 = 0.9 (or a skill_0.8 tag). The lever that makes a racing AI beatable. |
drift_grip | number | 0.2 … 1 | Rear tyres' share of their grip while drifting (the drift key, Shift or a shoulder button, held into a turn): lower slides wider; 1 no slide. |
drift_boost | number | km/h, 0 … 80 | Speed a fully charged drift adds when the drift key comes up; 0 none. |
drift_charge | number | s, 0.2 … 5 | Seconds of sliding for a full drift boost (a shorter drift gives part of it; under 30% none). |
