Invisible bike helmet a Swedish invention

My helmet after a crank failed while sprinting.

I predicted airbag protection in my 2008 futuristic story about using trucks as wind breaks on freeways. I think that will come to pass as well, but not in my lifetime.

Now some women in Sweden have developed an airbag helmet that wraps around your neck. That may be fine in Sweden where it rarely gets above freezing, but not elsewhere.

Still, it’s a start and they’re on the right track.
