echo the majority here - pure touchscreen infotainment systems are awful.
Moving from iDrive in my M135i to a touchscreen in a Octavia VRS, i desperately miss a jogwheel/joystick/input-system. With the iDrive I could jog the character on a bit, check the road, then keep moving my selection, check the road, etc. with minimal time away from the road. But, with a touchscreen, I need to concentrate more on where my finger is in relation to the screen, adapt its movement with the bumps, etc. and it all takes time away from the road. Scrolling through mp3s/radio-stations, easy in stages with a jog wheel, but dragging through lists with a touchscreen is just more distracting.
We all agree and understand that typing a message on a smartphone is distracting and it's good to be illegal, so how is a similar touchscreen any safer, just because it's built into the car? In that light, I honestly think they should be banned (or at least be deactivated when moving, and have an input device when on the move)
