Well that's not really designing for those users then. Your original comment said there's no way to interface with a screen safely while driving, but the other user said designers need to design for those dangerous users. I was wondering how you could do that in a safe manner (I don't think you can personally, and agree with the no-control-while-moving idea).

The other user said you had to design for what people will do; disabling all access and removing the choice to interact is exactly doing that. Disabling hands-on interaction above a certain speed but allowing voice controls might be another option.
The best I can come up with is transparently overlaying small information cues on the glass of the windshield, and using sound cues. I think in general the systems available to a cars HUD should be pretty limited and the controls should be on the wheel.
