We have a Suzuki that’s supposed to disable most of the touch screen controls when driving (including the TV/DVD and changing any navigation settings aside from zoom), but the used car dealer we bought it from informed us that he had already disconnected that sensor as a routine service to us...
I think the wording may some "certain cars" enforce it because after-market head units may not be connected up to the speedometer and therefore have no way of including this information.
