No, never been inadvertent IMC in 5000 hours; yes have been close to it, and have certainly flown in a lot of ****ty weather.
Maybe you're right and I have just been lucky over those hours. However what I do know is that I have been absolutely obsessed with never losing sight of the ground when I have not been able to go IMC, either prior to being instrument rated or since, but when going IMC has not been a viable option.
I've turned back many times and I've landed in fields waiting for weather to improve quite a few times. Maybe I'm more cautious than others, who knows.
No question this is out there to bite any of us any time, so don't anyone think I am over-confident or complacent that it couldn't happen to me. This is probably the biggest killer and continually needs the greatest efforts to avoid.
