I'm a hard-line rule following bicyclist, but I have no control over the other cyclists that blast past me at red lights. What are we supposed to do, render our nonexistent authority over them? I suppose I can say "please don't do that," but I try that and it has no effect.
Given how few of the riders are wearing helmets, they seem to at the very least be unaware of the risks they are taking.

Power is intoxicating. Being in a more powerful vehicle on a surface shared with other less powerful vehicles makes some people ignore others' safety, or discount the way in which their actions imperil others.
Anyone who has ridden a bike/motorcycle in regular traffic can attest to that experience around cars: you assume you are invisible to them. I've seen many high-powered cars/trucks/motorcycles swerving and accelerating dangerously around less powerful vehicles in traffic.
Similarly, I've seen motorcycles driving fast down bike lanes to get around car traffic.
It's a similar situation between the scooters and pedestrians on busy sidewalks.
This is exactly the reason why I ride my bike on the sidewalk even with a bike lane that is divided from the automobile lane with a white line.
I don't care what laws exist, I am not risking my life riding in a bike lane that is really seen as a large automobile lane.
That's why I believe they should be enforceable rules aka laws.
