but the ease of moving something on a screen vs physical switch...means that muscle memory could go out the window with a system upgrade. Since you can't touch it, you have to divert your eyes from the road to acquire the target and then move to touch it. We know what happens with distracted driving, this would only be worse. There's a reason so many controls have moved to physical buttons on the steering wheel. Your hands are already there, you don't even have to move to acquire the switch.
