What are the most effective ways to increase safety and security while commuting by bike, and why do so many cyclists seem to be stuck in a state of denial about the risks they face on the road every day, with some still refusing to wear helmets or follow basic traffic laws, despite the overwhelming evidence showing that these precautions can greatly reduce the risk of injury or death in the event of an accident, and shouldnt we be doing more to educate and incentivize cyclists to take these simple steps to protect themselves, rather than just relying on luck and the kindness of strangers to get us to our destinations in one piece, and how can we balance the need for increased safety measures with the desire to keep cycling a fun and liberating mode of transportation, rather than turning it into some kind of overly-regulated and intimidating experience that scares people away from even trying it in the first place, and what role should technology play in all of this, with the development of things like smart bike helmets and collision detection systems, and are these kinds of innovations going to be enough to make a real difference in cyclist safety, or are we going to need to see some more fundamental changes in the way our cities are designed and the way we think about transportation in general, in order to really make cycling a safe and viable option for everyone?
