Every detail of the road

An asymmetric multi-sine breath cycle drives a subtle body sway across yaw, pitch, zoom, and roll while the truck is stopped, fading out smoothly once you're rolling so it never fights the physics-driven motion at speed.

Amplitude scales directly with normalized RPM, so a lumpy diesel idle and a redlined climb feel distinct instead of the same generic buzz — the rumble builds and settles with the engine, not a fixed loop.

Vertical acceleration from the truck's own physics drives yaw and pitch perturbation in real time, so the camera reacts to the actual road surface under your wheels instead of a canned bump animation.

Per-corner wheel suspension deflection drives a seat spring-damper model, layered underneath road bumps — washboard gravel and a smooth highway compress the seat differently, and the camera reflects that difference. Spring stiffness and damping are tunable independently for a firmer or more sluggish feel.

Bumps belong to the road, not the clock — they arrive sooner and hit harder the faster you drive, and stay still when you stop. The cab bounces, leans and rolls over them, and rough ground like gravel or dirt is noticeably more broken up than asphalt.

Reads the game's own wheel_substance telemetry per wheel and applies a per-material roughness multiplier on top of the road-bump signal — pre-tuned for every base-game ETS2/ATS substance, with unlisted DLC surfaces falling back to a sane default instead of doing nothing.

Acceleration spikes at the moment of a gear change trigger a decaying shake — sharp attack, configurable decay rate — so shifting reads as a physical event instead of a silent gear-number change.

An RPM-threshold engine on/off detector keyed off telemetry (backed by a truck_electric channel) triggers a short, decaying shudder exactly when the ignition catches or dies — and is skipped entirely on electric trucks, where there's no engine to shudder.

A configurable high-frequency noise signal runs across every camera channel at all times — dialed low by default so it reads as texture, not distraction, but tunable up for a rougher, older-engine feel or down to zero if you'd rather not have it.

The camera glances toward the steering direction and holds mid-corner like a real driver tracking the turn, then fades out above a configurable speed so it doesn't fight highway-speed stability.

Head velocity on the vertical axis feeds directly into pitch, adding a bounce that scales with how hard the truck is actually moving up and down — most noticeable stacked with road bumps and suspension feel on rough terrain.

An overlay (default F9) exposes every setting across five tabs, with buttons to save to / reload from / reset motioncab.ini, and hotkeys can be rebound by clicking and pressing a new combo. DX11 only.
