Sure, I'd always blame the bike for my stupidity. Sounds more like a post from a troll. Things like this is why the created the Darwinism awards. I can't say that I've ever forgotten to latch any of my bikes ever.
I can say that I did have someone who thought it must be cool to unlatch my bike for me while parked outside. Unfortunately I didn't do a pre-ride check and I rode off a curb with no ill-effects before I realized it was unlatched. I did have the rear end try and ride parallel to the front though for a while. I learned to always check my bike afer that.
I'd be curious to see what bike he had the issue with. I've purposely tried my other bikes to see what ill effects I'd experience and they were all pretty much ridable but felt odd but not incredibly unsafe. I imagine if you turned the wrong way it could be an issue but in a straight line I didn't see it being a major problem.
