Comfort and Convenience
Remote start-up wakes the engine from outside the car, so the heater core or air-conditioning evaporator is already at working temperature before anyone opens a door.
Safety and Driver Assistance
When the driver presses the brake pedal hard, ABS senses a wheel about to lock and rapidly releases and reapplies that brake, so steering input still turns the car.
Multimedia and Connectivity
Android Auto uses the USB cable as the connection; the maps, messages and audio shown on screen are content generated by the phone and merely carried along that link.
