The pictures that I've seen of the various "saved my life" destroyed helmets have the polystyrene split apart - it's usually quite easy to split polystyrene if the force is applied the right (wrong) way.
- taeric 4y agoInteresting and scary. Curious what could cause the wrong behavior.
- ndsipa_pomu 4y agoI'd guess impacts at different angles. AFAIK bike helmets are tested for direct impacts via drop tests, so manufacturers may not care so much about how the helmet performs under different conditions - it may even be a good marketing gimmick to have helmets destroy themselves dramatically as people are more likely to share a picture along with a "saved my life" anecdote.
