In 1996 Mercedes launched a concept car called the F200 which uses a joystick to control the car.

Personally I don't prefer the joystick over the conventional steering and pedals to control the car. Maybe that's because I'm used to it.
In my opinion I don't think a joystick can achieve the feeling, precision and communication of a steering wheel, it's more disconnected.
I do believe that's it's possibly more easier and relaxing to drive especially in the city since you don't have to swing the steering too much to parallel park the car or turn in a 90 degrees narrow corner.
The joystick controls are great for handicapted people who'd like to drive a car but aren't fully able to due to their limits.
The present controls of a car are more involving. Manual shifting isn't possible with the joystick controls.
