How is a heads up display "accessible" for people with limited vision? In the web industry, we kill ourselves to make every color combination fully ADA compliant (in the US) and this involves a limited set of combinations. Not being familiar with the auto industry regulations (does ADA even apply?), I wonder how they (heads up displays) or even touchscreens could be considered accessible. Anyone have insight into how this works? Is the user possessing an active drivers license considered enough to exempt automakers from making their controls accessible to people "with disabilities".

Edit: May have found my own answers. ADA guidlines only apply to buses and other vehicles of that type: https://www.access-board.gov/guidelines-and-standards/transp... And most likely, not the operators.
