Thanks for the heads up OIC. I've managed to survive this far in my life without
needing GPS. Just thought it'd be handy once in a while, but certainly wouldn't be relying on it for emergencies in remote areas etc. To be honest, I thought the 4GS was a true GPS, but never really investigated much.
My only experience with GPSs is with my father. He's a "grey nomad" and uses it extensively travelling around Australia. I definitely notice now whenever he jumps in the car, his brain turns off and he relies solely on the GPS. He doesn't even watch or really think about where he's going. I was on the phone with him when they were in Tasmania and he was telling me they were on the east coast. I could hear my mother in the background say "No we're not! What are you talking about, we're on the north-west coast."
I took him to a dark site back in November. I'd only been there once, so when I picked him up, thought I would use the GPS for the first time to actually navigate. OMG I could have killed him. He kind of knew how to get half way there, so every time the GPS would say to turn, I'd start indicating to turn because I was listening to it, and he'd say "What are you doing, don't turn here". So I didn't. Ended up getting lost and took us twice as long to get there. And worse, he did the same thing on the way home.
