That's quite probable. They make it at least 50% bigger.
They also make it heavier...
Dosn't that make it safer for your head, maybe at the expense of your neck and spinal cord?
Assuming accidents happen too quickly tolet you actually do much before your head hits anything, adding mass to your head would tend to protect it and cause more damage to whatever it hit?
That's a big assumption.
The problem is bicycle helmets are not very strong. Therefore, they're almost irrelevent in accidents which _do_ happen very fast. Your body evolved over several million years as a plains dwelling predator, where running fast over uneven ground was an essential skill for survival; consequently, your reactions are finely tuned to cope with falls at normal cycling speeds.
They aren't tuned to cope with being hurled at the road at 60 mph, but then a cycle helmet isn't going to protect you in those circumstances either.
That's quite probable. They make it at least 50% bigger.
They also make it heavier...

Since on the whole you're tending to worry about hitting things that are significantly heaver (the ground, which includes things like lampposts, walls, etc), then this additional mass won't help.

Unless the thing you hit is an order of magnitude more massive than your head, or greater. Like the earth, for example, or a car, or a piece of street furniture, or a tree.

No I don't *think* so. Based on my non-statistical experiences quoted above (and that's why I think that bugger-all can be infered from them - statistics) - in a typical bicycle fall - that is the type that a bicycle helmet would protect against - the natural instinct is to fall such that you protect your head - hence fractured limbs and collar bones. In a collision where a motor vehicle is involved - that is the type that a bicycle helmet is unlikely to protect you in - then you are correct - things happen too quickly due to the speeds and masses involved.
Hence the motorcycle helmet has a different design and construction which affords protection where a motor vehicle is involved - that is every time it is 'used' (ie affords protec (Unless like me you hit the garage ceiling while wearing it!)
I'm sure that someone will point out the flawed logic in this!
