Thanks to bike sharing programs in San Diego and San Francisco, drivers will be sharing the road more often with cyclists. Bike advocacy groups immediately responded saying that this kind of bike helmet law ultimately discourages bike riding making the roads more dangerous for those who chose to bike among the cars. In March of 2015, California state senator Carol Liu introduced a new law that would fine adults for not wearing a helmet. Wearing a bike helmet is a personal choice and, so far, no states demand that adults use bike helmets. Adults riding bicycles in California do not have to wear a helmet while on a bike but that law is under review with a potential new law.
