An MSN editorial had some insight: "...Is that my cell phone buzzing, or the seat? 2013 Cadillac XTS (c) GMCadillac has a good idea here. Instead of annoying the driver with flashing lights and buzzing sounds from various active safety systems, it sends all those warnings to his back and rear end. ... The touch-capacitive dash is another story. See those silver trim pieces that look like you should touch them? Don't. They're just finger guides. The actual sensors are above them, which is confusing and frustrating. They're also slow to respond to repeated inputs, like adjusting the cooled seat or the fan speed, unless you're deliberate with your pace and timing. Who wants to think about how you touch a control, especially while driving? Lincoln already came out with this system and it's no different. It's like tapping a plastic post and wondering if some magic will happen. You also feel kind of dumb getting it wrong, which tends to happen when you're paying attention to the road. This feature needs to die." http://editorial.autos.msn.com/blogs/autosblogpost.aspx?post=3De29f4907-f964... Personally, I'm amazed that any UI designer for car controls would even think of making hand-eye coordination necessary for ancillary controls. I can control my old New Beetle radio and HVAC by touch, with very little learning. But my other cars with touch screens, any little bump and the wrong command gets invoked. And the voice control? I could go on and on, but in a nutshell, not there yet, adds frustration. ------------------------------
