Unfortunately, the vast majority of divers do "trust me" dives and nothing else. Once certified, most divers only dive on vacation, maybe 5 to 10 dives a year. All my diving now is done at resorts in Asia and I solo dive almost all the time, taking pictures. These dives are all guided with a short dive briefing and then off you go. This includes places like Palau, Yap, Truk, Bali and the Philippines. The only place I couldn't solo was in Sipidan in Malaysia and they gave me my own DM.
That said, all the diving I do is warm water, good vis and usually no overhead. Cold water, low vis diving is totally different in my opinion, I don't dive in Canada anymore...
