How about those guys who wear Nazi helmets as they ride their Harleys around?
Even our military uses a similar helmet design. After a *LOT* of testing we arrived at the conclusion that it’s pretty much the optimal design for balancing protection, visibility and weight. I remember quite a few people freaking out when the design was released
