Bicycling is more popular in Europe than it is in the U.S. and consequently there are more injuries from bicycle accidents. Developers in Sweden are working on an air bag for bikers that would fit around their necks like a scarf and go off whenever the rider is an accident. The scientists say that the air bag replaces a traditional bike helmet and is much safer. The air bags will be available next year in Europe. Wow. Check it.. What do you think?
