The trouble is that even if they only detach unexpectedly once every 10 rides you won't get motivated to stand up and hammer on your bike if you aren't confident with the safety of your pedals. I played around with the QR mechanism hoping to solve the problem, but never achieved success. I have wide feet and often wear wide shoes which likely exacerbates the problem.
Agree. Looks like it was added by engineers, not by lawyers ;-)
