Don't you think that's a little bit of survivorship bias? I'm sure there are plenty of cyclist who have been killed who 100% agreed and rode in that way, but they obviously can't speak on the matter.
Of course it is dangerous and potentially lethal when you get hit by a car, but how can you suggest that it's not beneficial to have measures in place that at least attempt to protect cyclist. It makes cyclist 'feel' safer, because it is in fact safer. Look at countries like the Netherlands that have excellent cycling lanes and safety measures. It makes drivers more aware that there are cyclist around them, and urges them to be more cognizant of their surroundings.
