From a security perspective, features like power windows, internal hood release levers, gas cap locks, and power locks are useful because they prevent unauthorized access to the vehicle. However, a Wi-Fi capability in a vehicle is not considered a useful security feature; in fact, it can potentially introduce security vulnerabilities like hacking risks. Therefore, the feature that is not useful from a security perspective among typical vehicle features is a Wi-Fi capable system, as it does not enhance physical vehicle security and may expose the vehicle to cyber threats.
