In 1992, I had a new Pontiac Grand Prix with a rash of radio controls on the steering wheel. Back in '92 it was novel and useful for volume and scan, but all the other buttons basically went unused. When I replaced the radio with an aftermarket one, all the buttons were useless. Today's cars squeeze 10 – 16 buttons (along with an airbag) for the stereo, cruise control, navigation system, tap-shift and even the air conditioner. The ease of control is getting cluttered, removing the "ease" for "confuse". Is this trend going too far? There's still plenty of real estate within reach on the dash.
