Thought the future of bike helmets were those poorly-ventilated Bern lids that everyone seems to be getting into?  Nope.  A duo of design students took a whole mess of venture capital, years of research, and a bunch of poor, innocent crash test dummies and created an “invisible bike helmet.”  The result?  A goddamn airbag that fits around your neck.  Also, it doubles as a scarf for the cool San Francisco nighttime ride.

The future is lookin' good:
