I've recently been driving a car that has touchscreen controls for turning on the heat, heated seats, adjusting the temperature, and more.<p>My biggest pet peeve with it is that I have to 1) wait for the system to "boot" and become responsive, and 2) click the acknowledge button on the warning screen, before I can do anything else. It's frustrating on a really cold day.<p>At least the defrost buttons are physical so I can get those going.
