I'm inclined to be sympathetic to cyclists, however, I strongly disagree with you. When people get to choose which of the rules they get to follow, they always choose the rules that benefit themselves without regards to those of others.
Cyclists aren't only putting themselves at risk, they are putting others as well, as is the case with anyone operating a vehicle. A cyclist choosing to ignore traffic rules can indirectly cause someone who expected them to follow those rules to take an action that greatly amplifies the risk of that cyclists' own decisions.
The fact that cities are not designed well for traffic that is not traditional vehicular should not be an excuse for people to put themselves and others in greater danger.
