There's a big difference between what is safe and convenient when you are sitting at your desk, lazily poking at the screen, and what is acceptable when you are barrelling down the highway, with the screen you need to stretch your arm to reach.
Interacting w/ a car touchscreen when you're on the highway isn't the brightest of ideas... Every car - even those w/ touchscreen - has physical buttons for top level commands (e.g. play the radio) that one could use via muscle memory or, at worst, a quick glance. Doing anything more involved that requires attention _while the car is in motion_ is just asking for trouble.
Exactly the point. But on some cars pretty much everything requires you to interact with a touch screen (cough, Tesdla, cough), and even if it does not, there's usually not enough buttons.
On my wife's Sonata, e.g., sure, you can switch the screen between map, nav. entry, radio, etc. with physical buttons. But after that it's all touch screen.Thank God they at least left alone knobs for the climate control...
Sat in the eTron lately while waiting for service. Two Nice, bright screens with haptic feedback. Very much fun, as long as I was playing with it on a showroom floor. But I shudder to think of actually trying to use on the road.
