Put me in the crowd for physical knobs. I work in the car industry and abhor tough screen interfaces. They are likely to be just as, if not more than, dangerous as using your phone while driving. It’s impossible to feel your way around a screen and look at the road. It seems manufacturers are starting to realize this and have hybrid systems with a large screen and knobs for common functions at least. Steering wheel controls are not enough if they car doesn’t have them or if they only have certain functions.
