The size means the helmet could also go in vending machines for people to rent at bikesharing stations. "To put traditional helmets in a vending machine, you’d need an enormous machine to hold any decent number of helmets," Wolff says. "With Morpher, it can fit in a flat drawer in an ordinary vending machine. You put in a credit card, and out comes a shiny new helmet."
The folding bike helmet that could improve bikeshare safety

The main problem I come across is moron's riding bikes with any lights at night. They are a danger to themselves, and other road users. Helmets make no difference to this, what is needed is enforcement of existing highway legislation by the police.
Bike helmets are not compulsory in Holland, a big cycle nation, yet their accident rate is much lower than other comparable counties. Separation of cycles and other traffic is more the solution, than hoping it stops little Johnny getting his head caved in by a 35 ton truck, but the rest of him get flattened.
Poor driving and cycling is also a huge factor, again going back to a wholesale lack of cops on the street, enforcing traffic safety/legislation, and a huge number of drivers/cyclists who don;t give a toss about other people on the road - pedestrians, cyclists, car/van/truck drivers.
