An improvement in bicycle helmet technology, lowering the probability a cyclist dies in any given accident, will lower the total number of cycling deaths per year. True or false. Explain
Answer
If there is a 2 in 10 chance that with current helmet technology you will die and 10 people buy the helmet, then, 2 people can be expected to die.
After the introducton of the new technology there is a 1 in 10 chance the cyclist will die. Once this occurs a few things can happen.
If same number of people buy the helmet, then, 1 person can be expected to die and the answer is TRUE.
If, since helmets are safer 20 people buy them because the safety is worth the disconfort of wearing one. Since 1 in 10 will be killed, 2 in 20 will be killed and the total number of deaths will remain the same and the answer is FALSE.
If you increase to 30 people buying helmets you can see the total number of deaths will increase and the answer is FALSE.
This is not even taking into account that each cyclist may behave more unsafely because their helmet is safer increasing the number of accidents.
Back to the original question, all variables held constant AND the number of accidents held constant, the number of deaths will decrease BUT in reality it cannot be determined.
I hope this makes sense.

What is a reasonable price for a bike helmet?
John
I would like to know how much is too much on a all-mountain/single track bicycle helmet and how much is reasonable. Also, any recommendations, the main helmet that I was looking at was the Bontrager Lithos which is $129 and I was wondering if this is a bit outlandish for a helmet or if that is what's necessary for a quality helmet?
Answer
In the U.S. every helmet regardless of price is tested to the same minimum standards. As the helmet gets more expensive the helmet gets better, lighter, and stronger.
$129 is a LOT cheaper than brain surgery or even a trip to the hospital from your helmet shattering on the pavement.
EDIT: OK, I guess I'll have to go into a little more detail. As I said before, all helmets must meet minimum requirements. The differences with better helmets, however, are staggering. First, cheaper helmets (asm entioned before) are good for ONE impact. That does not take into consideration that almost every accident involves more than one impact as you bounce off the road. That is part of the CPSC regulation.
Good helmets have internal webbing to allow the helmet to stay together as your head bounces off the road as cheaper ones come off your head. Cheap helmets break apart and fall away leaving your head exposed after the first hit.
Good helmets fit the head much more securely without using low durometer pads stuck to the inside, again making the safety fetaures of the helmet much more effective. Most decent helmets also have less abrasive straps and pinch-free buckles along with a much more effective and slip-free situation.
Good helmets also have a positive placing system of some sort to passively place the helmet in the correct position on your head. Again, VERY important feature.
Soooo, if all you want is minimum protection- if you don't particularly need your head for anything special- than a $25 helmet is great. On the other hand, if you tend to use your head (or anything that might be stored inside it) occasionally, that $129 is pretty cheap insurance.
