They are the same weight as regular cleats, and you can't tell the difference until you try to clip out for the first time. It is used as more of a motivational tool among racers, to put them in a 'do or die' mindset.
They were removed from the market after the gruesome death of the entire Lotto-Fuji squad in 1996.
Very funny but you really should include an emoticon to let the gullible know it's a joke. Anyway, I believe the first "clipless" pedals were made by Cinelli and intended just for track events. They did indeed require releasing by hand to remove your foot and would have been suicidal on the road.
