Yes but also why can't you just turn a knob to make it 68 (I don't know how much this is) and press a button for auto?

Okay here's a situation. You're on a road and it's gotten foggy and the roads are a bit slick because of the fog. All of a sudden the comfortable 68° temperature you have the cabin set to is causing your windshield to fog up. On a car with buttons and knobs you can just reach over grab it twist a knob or press a button and change the setting. However, with touch screen menus you have to actually turn to look at the screen, taking your eyes off the road in unsafe weather, to find the setting to switch it to defog. That's just one scenario there are at least a dozen others. Not to mention what would happen when it's snowing out and you have to take your eyes off the road to search a touch screen for the right setting on anything. Radio, brights, 4 wheel drive, etc etc etc...
