Carlos from Spain:
The problem with touch screens on vehicles is two find, one is the problem of the movement of the vehicle making it hard to hit the right button, but also that unlike physical buttons and nobs, you have to use your hand-eye coordination to direct the movent of your finger to hit the target, that takes a lot of concentration realstate for your brain, and while you are doing it you have to relinquish your awareness on driving for the duration and adjusting back to driving period since the brain cannot multitask those two tasks, that is why texting while driving is so dangerous. There is a reason race cars don't have touch screens and an F1 wheel is clouded with buttons, or a plain's cockpit. Unfortunately people are day by day getting more clueless about driving and more worried about doing other things while driving.
Well said, Carlos... 
This could be "compensated" by technology but nobody came up with a solution (so far). Probably not important enough for car manufacturers to "bother", especially since this wouldn't be something customers would really "experience" first hand. It would just "work" and this is not something people usually want to pay for.
