But both are distracting... Why are people so obsessed with getting directions by looking at a map WHILST DRIVING... I do occasionally use my phone as a navigator, but I only use the voice and listen to the commands, but I find it ridiculous how many people take their eyes off the road...

I don't understand why you'd want a touch screen for everything though - like I said, even for changing the temperature whilst driving seems impossible on a touchscreen device whilst driving...
