Three years ago, Rachel Hall was hit by a car as she was riding through the Park and Diamond intersection near Temple University in Philadelphia. The driver didn’t stop. She wasn’t wearing a helmet. She ended up in a coma for four months.
Her brother David and his friend Jordan Klein, then both engineering undergraduates at Virginia Tech, reacted to Rachel’s accident by setting out to figure out why people don’t always wear helmets, and trying to solve that problem. Now they are shattering fundraising targets on Indiegogo as they accept pre-orders for a collapsible helmet that looks something like a baseball cap.
