Comfort and Convenience
The electric tailgate drive answers a button rather than a pull: the occupant presses, and the motor sets the travel speed and stopping point instead of the arm.
Safety and Driver Assistance
On loose gravel or wet paint a locked wheel stops steering. ABS releases and reapplies that brake in pulses, keeping it rolling, though stopping distance can still lengthen.
Multimedia and Connectivity
The USB socket is the connection: a physical path for power and data. What plays through it is whatever the attached device holds, and the head unit must be able to read that format.
