Touchscreen controls sure are flashy, but as far as I'm concerned when employed in a multi-ton piece of machinery traveling at 60+mph they're borderline homicidal. I know I'm not the only one who thinks this way.
I'm open to voice controls. I don't like speaking to machines, but having machines speak to me is something I appreciate (for instance I always have my GPS talk to me, I never look at the screen) and I could see myself coming around on talking to machines. But a big old glorified ipad stuck in the dash? No way.
