Thanks. I do agree better infrastructure will make bike riding safer. In my opinion helmet is to bike what seat belt is to car. In general, I'd agree that people should make their own decisions and government do not need to make laws. But I have met couple of families who do not care about seat belt, even for their kids! How do you make such people understand the value of seat belt? Helmet is perhaps in similar situation. Not everyone is able to understand the value of safety devices and as a society we don't want them or their kids to get injured. Making something a law allows other to help such families - we can simply call out "it's a law"
