The annoying thing for me is that the touchscreen in an automobile doesn't preclude it form having physical controls, often the physical controls are just very poorly thought out.
My 2015 Nissan Leaf has on the face of the steering wheel two 2-way rocker switches, a 3-way rocker switch, what looks like a rocker but is actually two buttons, and five other buttons. This is in addition to the two control stalks that have a dizzying array of positions and knobs themselves.
Three of those buttons are for dedicated features of the infotainment system I will never intentionally press. The answer/drop call button could also function to invoke the voice recognition feature and eliminating the dedicated button. The cruise control utilizes a 2-way rocker and two buttons, it really could be reduced down to a single 3-way rocker.
Infuriatingly the model with the infotainment system, an upgrade, replaced the knobs for volume and temperature control with buttons?! You might think it's to reduce space for the infotainment system but when you look at the two consoles side by side they're proportional spacing is the same.
The infotainment system has two to three physical buttons dedicated to features you shouldn't be using while driving and would better hidden behind the menu button. Of the physical buttons that are arguably usable, there are two that I will again never intentionally press. They'd have been better off making the buttons color/symbol coded and function programmable like the buttons that flank the sides of ATM screens.
