Yeah. That is a bit scary. People got used to think that plastic and wood are pretty weak and fragile materials (compared to metals). But people believe that metals have much more strength (even if in reality they don't - in case of some metals and alloys), so I wonder if they start using printed metal parts in their cars (or similar), because it is much cheaper (but "it is made of metal, so must be strong enough!").

Will this cause more accidents?
