it's not automatic disengage... tenno is just pointing out the fact that in an event of a crash while the bike is moving..most likely the forces involved would have been enough to twist your foot out of the pedal even with the strongest tension setup...
on MTB... here is a difference between the Shimano cleats in the old days.. there was a uni-directional one and a multi-directional cleat that allows release via inward, outward and even very heavy upward jerks... for in case you flip over the bars and crash which happens quite a lot in mountain biking...
well, nothing more can be said then get used to it.. the percentage of riders who "never crash" on initial usage of clipless pedals are very little... no matter how much you try on the trainer.. it just does not work because your mind is set on releasing the foot from the pedal while on the road you forgot about it until you come to a dead stop... then you panic and shit happens..
if you are lucky.. it'll never happen again, else.. a few more times and you'll learn...
just think about your foot every time you think of stopping.. until it becomes automatic...
I think the mind is so used to just lifting up, instead of pulling to the right or left.
More practice today between the walls of my corridor. Still not used to unclipping when body is tipping over to one side. At least this time just the shoulders hitting the wall instead of the road pavement.
It's also harder to unclip at the 12'o clock position because the legs are bent. Far easier to unclip when the foot is near 6'o clock position. practice more.. more more..

That's why tilll now I still using normal pedal with normal shoe haha.. Furthermore lighter pedal too.
For one side of the foot, just weighted them with the portable scale :
Nike reax running shoe=350 grams
Metal normal pedal= 200grams
=550 grams
Shimano R064+time cleat=360 grams
Time RSX first pedal= 260 grams (from website)
= 620 grams
Yea.. you're right. So it's slightly heavier to go for the clipless pedals. I have yet to see if they actually help with pedalling or not.
