The fact is this is a dangerous and uncertain world and it always has been that way. There are no absolute guarantees in life. There might have been a cyclist sitting and having a meal in New Zealand thinking everything was safe and beautiful, and then the earthquake struck, also Japan, Indonesia 7 years ago with 250,000 suddenly killed. People die unexpectedly every minute of every day all around the world. It is a constant fact of life and death. The optimist takes the view that such calamites will befall the other guy, but not himself. However, to everybody else on the planet the optimist is the other guy too. We are all the other guys / gals that can meet sudden death. Cycling is one way accidents can happen. Of that there is no doubt. Being vigilant and watchful, and internalizing safe cycling procedures can go a long way toward keeping yourself safe.
This is not to revel in the negative. It takes only one drunken person to end your life or ruin it to where life is worse than death.
Also, when motorists push through your legal ROW with the obvious attitude of get out of the way or die, you have to come to some kind of realization of how extremely belligerent, criminal and offensive that really is. If you were cycling down a sidewalk and someone was there swinging an axe back and forth and said you had to stop or go around him or lose your life, what would you think? That would be criminal, right? But, people can do essentially the same thing with their cars and trucks, and that is supposed to be acceptable. This is not a perfect world, OK? Despite the image people from la la land need to project, there is a whole lot wrong out there, and riding a bicycle does not make it go away. I personally think that maps from ACA would tip the odds more in your favor if you use them on long or short tours by bicycle.
