| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Automobile (Prototype) (automobile_prototype) | historical_predecessor | 78% | expert_inference | Experimental self-propelled road vehicles precede the practical Benz Patent-Motorwagen lineage. |
|
| Internal Combustion Engine (internal_combustion_engine) | required | 90% | textbook | The scoped broad automobile node is anchored to Benz's gas-engine vehicle, so an internal-combustion engine is a hard component dependency. |
|
| Steel Production (steel_production) | common_dependency | 58% | expert_inference | Steel and metalworking support practical vehicle frames and mechanisms, but steel production is not the date-defining invention. |
|
| Vulcanized Rubber (vulcanized_rubber) | enabling | 62% | expert_inference | Rubber tires and belts enabled practical road-vehicle operation, but the broad automobile concept is not scoped to later pneumatic-tire mass production. |
|
| Roads (roads) | common_dependency | 60% | expert_inference | Road infrastructure is contextual operating infrastructure for automobiles rather than the invention itself. |
|
| Petroleum Refining (petroleum_refining_fractional_distillation) | commercial_or_scaling_dependency | 62% | expert_inference | Liquid fuel supply supports automobile operation and scaling, while the broad practical vehicle is anchored to the 1886 Patent-Motorwagen. |
