Data Reliability
This ranking represents how reliably the vehicle or OEM processes data requests. A rank of 1 indicates the highest reliability. Command Reliability
This ranking measures the effectiveness with which the vehicle or OEM handles command requests. A score of 1 reflects the most reliable command execution. N/A means there is not enough data to provide a score. Data Freshness
