To be fair,... bicycle riders wear those little noggin' lids,.. and feel safe..
Of course they do get hit and die occasionally, too...
At lower residential speeds, you do have more control of how you land in a crash... you can try to protect your face...
At speeds over 50mph, in a crash,.. you're functioning on your lizard brain...
I'll bet, those bicycle helmets are equal in protection to half helmets,... and they have better cooling...
I've had two major crashes on the street...
One, I slid it out,and never hit my head at all...
The other,.. I kissed a truck grill, and ricocheted face first into pavement...
