I rent cars a lot when I have to travel, and I've grown to hate anything "touch" in a car. Several manufacturers have adopted touch-based controls, even outside of a touch screen. For example, I had a Toyota Avalon rental a couple of months ago, and I was constantly, accidentally pressing buttons because I brushed them with my hand. When a car is in motion, it's hard to steady your hand. With touch controls, I find that I have to plant a finger somewhere as an "anchor", then engage the touch inputs with another digit. What a horrible mode of interaction.
