I read somewhere that even motorcycle helmets are really only rated for low ish speed offs to protect when your head hits the tar mac. Think in a collision with a vehicle we would need some sort of auto deploying airbag to have any real effect, not a couple of hundred grams of polystyrene and plastic.
That said, I always wear one because: - it is white, says cannondale on it and matches my bike, and I am a tart like that. - I would rather have that "if you weren't wearing a helmet it would have be x- times worse" talk with the doctor than have the doc apologising in hushed tones to my wife.
Not a scientific example, but see that top gear episode where James may gets pushed over by the tow rope, falls backwards from standing height an clouts his head and got pretty severe concussion. Basic physics, helmet would have spread the impact area and potentially lessened the injury. I figure I am a foot higher than normal on the bike and clipped in, so might wanna protect my head.
