As for Mountain Rescue Teams thinking that mobile phones might be a negative due to recklessness. That isn't true, people have always been reckless.
You're misrepresenting what I said, which was viewing it as a mixed blessing. I've certainly read reports of rescue teams seeing an uptick in call-outs, sometimes erroneously, because people have phones with them. But, of course, everyone is pleased for the lives that have been saved because people had mobile phones and could accurately give their location.
