I can't believe some of the choices they make with touchscreen. Some screens in my car have tiles -- large squares where 8 of them fit on the screen -- which are easy to press. Then there is the phone number listing for dialing, which is are line items which only fit 4 or 5 per page, they are wide, but short. So if you're driving and the road isn't completely smooth, it's very difficult to press the correct line, and requires a lot more attention on the screen.
