Capacitive 'button' replacing buttons.
Driven in part by the whims of designers, who want more cleanly styled interiors, automakers have been subbing in smooth capacitive 'buttons'—essentially special sensitized areas along the smooth surface of the instrument panel. Yet based on our experience with these types of controls, they’re simply too unreliable. They don't work in the cold; they get laggy at times; and they inexplicably work better with some people's fingers than with others. The ones in the Toyota Avalon are the best we've used so far, but why not rotary knobs? Likewise, capacitive sliders aren’t doing a great job yet in replacing dials and knobs. In the words of one of our other editors, “What's the point of losing buttons if you lose total control of the vehicle while trying to mute Mariah Carey?”
