Hmm. I gues I am "special" as well as it has never happened to me.
When I bought my first clipless pedals 15 years ago, the lbs owner took me outside and gave me a 30 second demonstration. "Down and out is all you have to know" he says. "Down" places your weight and center of gravity low and to that side. "Out" with your heel unclips. Easy. I thought about it for two rides and it has been second nature since.
So, it doesn't happen to everyone.
