While this is certainly not empirical one of those cracks was in my helmet when I was flipped off my trike (rear wheel lockup) at about 20mph. 6 broken ribs but no discernible head injuries by the ER physician test for concussion. One bike accident victim arrived DOA with massive head injuries, no helmet said the paramedic who wheeled him in. Any helmet is better than none.

See, you want a helmet that effectively compresses and reduces the deceleration forces over time.
Not one that just cracks into pieces when it hits something. The reason why this happens as a bicycle helmet simply can't absorb that much energy. A high quality motorcycle helmet is a magnitude of order more effective than a bicycle helmet, but unfortunately very impractical if you are planning on pedalling.

[/sarcasm]
Compared to a motorcycle helmet, most bicycle helmets are almost as bad as those leather caps in effectiveness.
If you are just wearing a bicycle helmet, you are still compromising your safety. If we are rational, we need to accept the risks we are taking.
