Big difference with motorbike helmets: those are integral helmets, protecting your entire head. Cycle helmets only help against direct hits on the top of your head. Crashing head-first into a car or tree (or getting a tree branch on your head).
German consumer organization tests showed that lots (60% or so) of the helmets for sale in Germany didn't even meet the head-on-collision tests as the testing isn't done by an official institute...
Wearing a cycling helmet makes sense when you've got a good chance of hitting something straight on. Like mountainbiking and hitting a tree or speed cycling at 50km/h, bend over your handlebars.
Kids? Regular cyclists? Mum with groceries? No way. Or at least: other things are more effective. Like wearing a cycling helmet as a pedestrian (who apparently hit things with their head more often!).
