Tires interact with the snowy surface - Signal surface changes in advance and keep grip behavior consistent. - [DiRT Rally 2.0](https://store.steampowered.com/app/690790/) ## How it works Changing grip connects line choices to surface conditions and the next section rather than one constant cornering speed. ## Variants ### Mechanic variants - Gravel increases braking uncertainty. - Ruts guide wheels and restrict line changes. - Reconnaissance describes a hidden turn. - Water changes the usable safe pace. ## Design example A driver slows before a crest because notes warn of a gravel turn immediately beyond it. Prototype check: Test surface appearance against actual grip and cue timing before blind sections. ## Context and limits Vehicle mechanics connect controls, momentum, routes and machine condition; the chosen simplifications should stay consistent. Each overview separates player actions, state changes and alternative rules. Examples are hypothetical design scenarios, not claims about a named game. A prototype check states an observable question for the next iteration. Existing detailed references remain separately linked from the direction map. ## Connected materials - Sources in the selection: [Godot: physics introduction](https://gamemechanics.pro/en/resources/#resource-godot-physics) (key: resource/godot-physics) ## Sources and provenance Original bilingual editorial overviews authored for gamemechanics.pro on 2026-10-20 and reviewed on 2026-10-21.
