Top variants of many cars today and most luxury cars in the market are equipped with steering mounted controls. These controls can be used to control the stereo and a host of other functions depending on the car and the options available. High end luxury cars come with steering mounted controls for automatic cruise control.
Steering mounted controls allow you to control the stereo, make and receive calls on Bluetooth stereo systems without taking your eyes off the road and staring at the display screen of the stereo unit on the dashboard. Changing radio stations without taking your hands off the steering wheel can be a huge safety feature in case of a sudden manoeuvre that has to be made in case of an emergency.
