A marvel of redundancy
I believe it was Motor Trend that called the Prius steering wheel as a "marvel of redundancy." Redundancy isn't usually a desirable trait, but in this case it's fantastic. The dinky little steering wheel duplicates almost all the daily day to day functions you would need found elsewhere on the dash, such as navigation controls, switching screens, volume, climate control, etc.Like the smart key, the steering wheel is just one of those things in a car you take for granted as being low tech and otherwise useless. All they are used for in most cars is for (oddly enough) steering, an airbag, and a horn. But if keeping your eyes on the road and your hands on the wheel are the two most important things to safe driving, why are all the controls on the dash? The Prius shuns this notion and jams (in a logical fashion) numerous controls onto the wheel. Once you get used to it, almost everything is at your finger tips.
The engineers put some thought into this. Obviously you can't mimic every button on a steering wheel, so they had to pick their battles -- and they won. I'd say you can perform 90% of your normal driving tasks without ever having to move your hands off the wheel. The things I use the most are volume (for both audio and phone calls), info (energy monitor), map (navigation), and temperature controls. Like the smart key, it makes so much sense that I hope we see more of this in the "average" car soon.
