Whats the point of even wearing a bike helmet if its not going to protect the brain and skull from serious injury in a high-speed crash? Are we just pretending that a thin layer of foam and plastic is going to magically save our lives? Dont get me wrong, Ive seen the safety tests where a helmet is dropped from a few feet and it doesnt crack, but what about when youre going 25mph and hit a car head-on? Is that really going to make a difference? And another thing, why do helmets have to be so ugly and uncomfortable? Cant we just have a helmet thats actually stylish and doesnt make us look like a total dweeb? And whats with the safety certifications that every helmet seems to have? Are those just a bunch of meaningless stickers or do they actually mean something? I mean, Ive seen helmets with like 5 different certifications and they all seem to be saying the same thing, that the helmet meets some arbitrary safety standard. So, whats the real difference between a $20 helmet and a $200 helmet? Is it just the brand name and the color scheme? And dont even get me started on the whole helmets are only good for a single impact thing. So, if Im in a crash and my helmet saves my life, Im just supposed to throw it away and buy a new one? Thats just great, another way for the helmet manufacturers to make a quick buck off of us cyclists. So, I guess what Im asking is, how do bike helmets actually provide protection for the brain and skull, and are they really worth the money?
