yes. totally agree. I LOVE adaptive cruise control, but also love/need the ability to work the music and environment selection buttons - switch stations, switch cds, change sources, turn heat up down etc - with just an instantaneous glance followed by touch only.
My Honda Accord is pretty good with this -- it has a lot of smart features, but also has buttons for pretty much everything I need (real clickable buttons or knobs, not touch sensitive buttons that give no tactile feedback)
The voice response system is horrible, if I have to use the Honda navigation, I almost always need to stop so I can type in my destination. But since I use Android Auto 99% of the time, it doesn't really bother me.
I don't think they're underrated, they're much more expensive than drawing pixels on a screen, especially now that screens are required, by federal law (back up cameras). I imagine we'll first see them reappear in luxury cars.
