You aren't an Australian, so you wouldn't know how bad the maps are here... They're pretty freakin bad!
I'm a fanboy, but I'm not going to lie... Apple maps are hopeless down under.
Embarrassing for mindless idiots...? In Australia, we have 4+ hrs gaps between towns (even longer). If you don't know where you're going, you're going to rely on your maps. If they aren't accurate, that's the fault of the map provider, not the user.
It's not like he drove randomly into the outback. He drove along a highway to a town, and his maps told him to turn (there aren't a lot of signs on some of our roads) so he wouldn't have had any reason to assume he was going the wrong way.
I think the thing we all learn from this, is maps aren't perfect. I don't know why you're on the defence of Apple? They stuffed up... Apple are human too... Why do you think Apple apologised and a guy got fired over Apple Maps? Because they're really bad. lol
Kudos to you for trying to educate him about anything outside of the US but I think it's going to fall on deaf ears. He's too focused on defending his technology choice and his favourite company to understand the issues that the other 95% of the world are facing.
