A big orange "PANIC" button in the middle of the dash really won't work.
The lawyers will make sure that the Owners Manual has all sorts of warnings that the Panic Button is not meant to be used in actual emergencies, that one should avoid any actions that could lead to an emergency, and see your dealer for more information.
But few people read the Owners Manual, I may be one of the last, and I will die off one day.
So the lawyers will insist that all cars equipped with a Panic Button MUST ALSO be equipped with the factory NAV System.
So in an emergency, the hapless clueless motorist punches the Panic Button --> The NAV screen switches to a disclaimer page, actually two pages of small text, that require the user to read it all then click an "I Accept" box, which if performed, reverts half of the NAV system screen to show the location of the nearest Trauma-Level Hospital. The other half of the NAV System screen displays the latest maintenance specials now going on at their dealer (10% off any major body work with coupon, limited time offer; Remember, fresh coffee is always available in the Customer waiting area).
But if they instead select "I Don't Accept", the NAV System switches into Chinese display mode, or religious programing, it's random.
