Comfort and Convenience
A keyless entry system has no intensity setting: it either recognises the key carried nearby and unlocks, or it does not. Single-zone climate control, by contrast, is adjusted continuously through temperature and fan level.
Safety and Driver Assistance
The electronic stability program acts only once wheels begin to deviate from the steered path, trimming engine torque and braking individual wheels. It cannot extend available grip, so following distance still determines whether a gap exists to use.
Multimedia and Connectivity
A USB connection carries data as well as power, so track and folder names from a connected device can be read by the car and selected through its own controls rather than handled on the phone.
