Comfort and Convenience
With the keyless entry system, carrying the fob in a pocket is the only input: touching the handle wakes a sensor that unlocks the door, and the fob may stay out of sight throughout.
Safety and Driver Assistance
Lane departure warning watches painted lines and alerts the driver before an unsignalled drift, whereas the stability program intervenes only once the car is already sliding, applying brakes itself.
Multimedia and Connectivity
A USB socket confirms a physical port, not what it carries: charging current, file playback and phone projection are separate capabilities, and a given socket may support only some of them.
