Yesterday, I saw an article from a car show. http://www.popsci.com/cars/article/2013-01/detroit-auto-show-2013-infiniti-q50-augurs-future-without-steering-wheels
It was an Infiniti that was being shown... and it steers with a joystick. The article said that the car would be available this year (at the end of the summer).
Having died in video games so many times while utilizing a joystick, I just don't trust a joystick to control my vehicle.
A Google search for "no steering wheel", brought up a bunch of matches from earlier years and from other vehicle manufacturers. It scares the hell out of me
