I heard this rumor now that clipless pedals with a narrow platform like Eggbeaters or maybe Frogs are a theft deterrent because most thieves don't wear cleated shoes, and wouldn't be able to pedal a bike with these away.

I don't think this is true, because its not hard just to pick up the bike, chuck it in a truck, or car rather than ride it away in the sunset.

Any truth to this?
