Novelty helmets have been around for a long as motorcycles - I'm surprised this hasn't been addressed in detail long before now...
It has over and over and over again!!
The problem in my assessment is that the studies are biased and produced as part of a larger agenda- reinstituting mandatory helmets laws in all states. Don't think for a minute that the helmet manufactures aren't complicit in this. They miss the revenue!!
What I would support is a unbiased study that drills much deeper into the reasons for injuries.
In numbers, crashes are down year over year as are the percentage of crashes/riders.
The last time I looked at a credible study the following stats were true;
1. Over 60% and growing of motorcycle accidents were attributed to excessive drinking.
2. A large percentage of the remaining 40% was due to new riders inexperienced in riding.
3. Another large percentage of the remaing 40% was directly attributed to the motorcycle rider being struck by a car (T-Boning, turned into lane changes--etc.
The numbers won't add up to 100% but you get the drift.
ALSO, it is important to know that a helmet is not designed to protect you in a accident above 20-25 mph. They actually conduct what is called a drop test from a ladder.--14' . Also, if your helment was used in a accident--cracked or not it is rendered unusable and you are supposed to buy a new one. I am not sure of the current thinking regarding time but a helmet needs to be replaced if worn over 3-4 years. The padding breaks down over time rendering it marginally useful for it's intended purpose.
Helmets have been the cause of death or significant injury in a accident. Our bodies are not designed to handle say whiplash at speed with a helmet on. Your neck can be broken because you were wearing a helmet.
THE GOOD NEWS---Over the last 20-30 years there have been significant improvements in helmet design as a result of meaningful dialog like this with credible information. As a result helments are considerably lighter, stronger and make the user safer. Think of the old Bell Helmets verses today as an example.
Jet pilots, racers of all kinds and yes motorcycle riders are the beneficiaries.
I have always thought that if say Harley or Victory--etc in partnership with the helmet manufacturers would come up with a hard bag NOT TOUR PACK that legal helmets would fit in and allow them to be locked up when not in use, there would be more buyers/users.
LASTLY, develop some meaningful helmet crash/impact standards that provide value.
It's somebody elses turn 😃😃
