I would be very interested to try how good it works. I think it's going to be much harder to make a realistic driving feel to a joystick than to a steering wheel. But I also can think of some worst case scenarios that could happen. For example if you have a dog on your back seat and it gets interested in this "toy" your holding in your hand. The dog could jump to the front and get a good grip with its teeth and then shake the "toy" hard.
BTW I didn't remember that all german car concepts don't look good... That must be one of the ugliest concept cars from MB. The rear looks like a Peugeot. And those rims!
