If I'm expected to operate controls while simultaneously operating a vehicle (regardless of whether it's on autopilot or not), I want to be able to do it by feel. At worst, a glance then by feel. I want to know by feel that I've got the right control, and I want to know by feel that I've moved it.
I rented a Peugeot which had a touch screen for everything including climate control. Bouncing around the wilds of Scotland on what passes for an A road up there, the amount of concentration it took was downright dangerous. I ended up having my girlfriend work the damned thing. A car should not need a first officer.
Less Apple, more Fisher-Price, please.
