You do realize that there are these things called PHONE CHARGERS that can be plugged into cars nowadays???
And perhaps these "adventurers" weren't EXPECTING to be heading into the WILDERNESS when they thought they were following driving instructions toward a CITY.
But yes, you're right, anyone putting faith in Apple Maps nowadays after all the public warnings and all the negative publicity is an UTTER FOOL. Not to mention it only takes less than 5 minutes using Apple Maps in a moving car to know it's absolute RUBBISH.
