My experience as a lifelong pedestrian is that cyclists consider themselves "vehicular" when it suits them and "pedestrian" when it suits them. The upshot is that they want to claim all the rights and none of the responsibilities.
Once you're a bicyclist you'll realize that there are actually very few rights or responsibilities granted to a cyclist.
It is the most libertarian - maybe Hobbesian - of the transport forms and that's why bicycling remains a small group of people who behave in a bit of a vigilante way. For example, you say that bicyclists behave "vehicularly" and "pedestrianly" but that's also a product of the fact that bicyclists have almost no space officially designated for them, so they have to make up the rules as they go along. Bicycling doesn't have any licensing or standards so you'll see anybody take to the road on a contraption of any quality and behave in any way they want as doesn't endanger their life (by their definition of what's life-endangering). If your bike is stolen, there's no way to track where it went. If you damage your bike in an accident, there's no insurance for you to fall back on.
The best way to improve behave bike behaviour is to improve the infrastructure for bicyclists. If you visit a city where they've spent a lot of effort to create designated spaces for bicyclists, you'll see that cycling and cyclists are a lot more civilized.
