Benchmarking LLM Safety for Vehicle Voice Command Authorization
The paper (arXiv:2609.19630v1) introduces a 202-scenario benchmark and seven-class taxonomy to evaluate pre-action authorization decisions for vehicle voice assistants. It evaluates two local open-weight models and three API-based LLMs, reporting decision alignment from 40.1% (Llama 3.2 3B) to 89.1% (Gemini 3.1 Pro Preview), finds API models at 83.2–89.1% with no significant differences, observes two to three False Executes among 161 non-execution scenarios, and concludes that structured LLM decisions alone are insufficient—deployments require an independent enforcement layer to verify permissions and vehicle-state constraints.
KEY POINTS
- The paper (arXiv:2609.19630v1) introduces a 202-scenario benchmark and seven-class taxonomy to evaluate pre-action authorization decisions for vehicle voice assistants.
- It evaluates two local open-weight models and three API-based LLMs, reporting decision alignment from 40.1% (Llama 3.2 3B) to 89.1% (Gemini 3.1 Pro Preview), finds API models at 83.2–89.1% with no significant differences, observes two to three False Executes among 161 non-execution scenarios, and concludes that structured LLM decisions alone are insufficient—deployments require an independent enforcement layer to verify permissions and vehicle-state constraints.
- This matters because mapping natural-language requests to vehicle controls is safety-critical and the study shows LLMs still produce dangerous 'False Execute' errors, so independent enforcement is required before invoking vehicle functions.
