I slammed on my brakes just before the ditch grabbed my front tire, the bike flew backwards between my legs and the next thing I know I'm jogging down the trail instead of biking it. I don't really know how I managed that maneuver, but I can definitely say being clipped in did not slow me down any.
All jokes aside, you are absolutely right Bin. I have went over the bars and ended up walking/running down the trail. No idea how I got out of the clips. After using them awhile, it just happens. I don't really see it as a detriment or issue at all really to be clipped in. If I need to get unclipped, I do. It just happens.
I liken it to alpine skiing. When you need your skis they are on your feet. When they need to come off, they come off. Again, comes to preference of the rider. Neither is better in my opinion. Clips are more efficient pedaling, yet I have gotten my but kicked by riders on flats on XC trails. Does that mean flats are the better tool in this situation? No. It means that rider was enough better than me to more than compensate for the less efficient pedal set up. I have also seen clipped in riders on the most gnarly technical features around, and use the clipped pedals to maneuver the bike around. Doesn't make it better, just what that rider is used to doing.
The real advantage I see in flats is if you prefer to take your feet off the pedals for your fun. As in you like to get your feet off the pedals while in the air. Or you like to put a foot down on corners to balance rather than use your bike. Stuff like that.
And it is fun to pick on others choices as long as it is good natured
Like the goofy guys with mustache bars, or 26" bikes, or dinglespeeds, or full rigid, or full susser, fat bikes. Oh wait, I might fit into a couple of those categories
If it is biking, I think it is all good. I love it all :D
