I used to ride this portion as far right as possible, and take up as little road as possible. This allows cars to pass freely. But, a driver would rather crash into a cyclist than suffer a head-on collision, so occasionally a car would pass waaaay too close, since there just wasnt room given the situation of the oncoming traffic.
Now, I ride about 30 cm out from the curb. This is just far enough that there is no way a car can pass you while there is oncoming traffic, but not so far that it's difficult for them to pass when there is not oncoming traffic. Also, it gives me some buffer, and allows me to pull right if I sense that I'm going to get hit by some dare devil.
Do as you would be done by... I want cars to treat me with respect, and so I treat cars with respect. For example, depending on the situation, I think it is not appropriate to pull up to the front of the line when you're at a red light. If there's a bike lane, or a wider shoulder, such that you don't hold up cars, fine--go ahead. But if the cars you passed at the traffic light will now have to wait for you and be unable to pass, then I think that's inappropriate.
Your first point is one maintained by civic officials and cycling advocates in both London and New York. I haven't really cycled in LA or adjacent rural areas since my teens, but I have ridden in New York since being an undergraduate in the 90s so in the spirit of stating basics for new riders and cycling politics in general, I'd offer a few more observations.
In terms of taking the road--if necessary--that's an absolute: it's far easier to control the situation and the worst that happens is you have drivers honking at you. I haven't done this in some years, but with the time to kill, I'll come to a dead stop in the middle of the road and dismount facing their car until they're shamed by other drivers and pedestrians. (Again, this won't quite fly in most parts of LA). Drivers in cars aren't (mostly) driving scared, there's no reason you should. Especially in today's digitized world: if they're that pressed to be someplace, they're doing something wrong and need to reassess their lives or traffic management in general. (Anecdotally, traffic in SF became steadily less aggressive during the tech boom in the 90s).
I'm also familiar with the studies on helmets and experienced (or perceived) that to be the case during the time I did acquiesce to familial pressure and wore one for awhile. The one crash where I might have benefited from a helmet might also have snapped my neck rather than leaving a few repairable contusions and a concussion, so it's an open debate.
In terms of city riding though: it's much safer than 10 or 20 years ago--or at least somewhat safer and far less hostile. But many cyclists don't help matters.
So, for those new, don't assume that because you're in a bike lane that anyone else actually recognizes its right to exist. Again, more do than even two or three years ago, but don't ride as if protected and safe within the rules of your road.
Don't ride in lateral groups unless you're on a full dedicated street in a park. Everything else is potentially hazardous for you and other cyclists. More generally it's selfish. So, by extension, don't even treat dedicated bike lanes as a living room with your friends and family--even if that's who you're riding with--people cycle for multiple reasons, not all of them yours.
As mentioned above, don't overtake or undertake a car in any intersection if they have the least opportunity to make a turn without signaling. Don't even pass one in a lane unless you've looked ahead and can see that there's no reason for them to suddenly change lanes on you. In terms of other cyclists, think exactly the same thing and if you're fresh and eager to show how fast you are, don't pass another cyclist in a congested area unless you've looked more than 20 feet in advance and can see that you're not about to hit a situation that brings you to a skidding halt with the other cyclist(s) now inconvenienced and more aggravated behind you.
More specifically in terms of traffic, this is not a video game, it's a real, physical, constantly changing dynamic: watch the cars in front of you as if you were driving: if they show the least hesitation or erratic tendency, presume that they're about to do something and leave room.
In many (US) cities, if hitting an intersection at speed where a car from the opposing direction wants to make a left hand turn in front of you, don't assume that making eye contact will keep them in place. More often than not, it's the opposite, they'll take that as permission to go--presumably because you only have to brake a bicycle.
In New York, yellow cabs are now generally more responsible than green cabs.
Unless making an organized and defensible political statement against the hugely wasteful monoculture of automobile designed cities and streets, do not ever ride the wrong way down a street--even if it's your home block: it's lazy, selfish and again, potentially hazardous to you and other cyclists.
If it's down to you, me and parked and speeding automobiles, I'll knock you over to take the hit I know, rather than be nailed from behind by a car while trying to give your stupid @ss maneuvering room. 999 times out of a 1000, I'll just control that space forcing you--illegally and idiotically--toward the oncoming traffic. At which point you'll dismount between parked cars, get on the sidewalk and cross the street. As you should.
Don't run lights against any car or pedestrian who has the right of way. It's detrimental to cyclists rights and antagonizes everyone. And these days there are enough doing it that you're also inconveniencing other cyclists. If you thought you were contributing to civic progress: that isn't
As others have stated, assume you are invisible, but more specifically, ride as if you were following the rules and distances and rhythms of the road: head check, signal as needed, however subtly, don't swing out around double parked vehicles (I watched a woman get hit head on by a delivery truck doing that).
In general, don't be fearful or reckless, but rather aware of what poses a threat to you, but also how you impinge upon others and learn from other cyclists who clearly have better control of their bikes than you do. But also be savvy about controlling the road. In certain contexts, despite what's painted on the street, it's far safer to pull out just ahead of the crosswalk where you won't inconvenience pedestrians or be hit and/or abused by turning or merging cars. Similarly, in tight one way situations, it's often better to ride on the left side of the road as both drivers behind can see you and the odds of being doored--when it's too close to stay consistently clear--are likely less and generally easier to anticipate.
In terms of lights, I've worn them since living in London--which necessitates it at night, but also because people asked me to, politely, rather than resorting to mandate.
I use them in New York not only because I want to be seen in certain areas that I ride, but as an assertion of my right to be on the road, and to be as accountable as possible in any contested situation--give people as little room as possible to say they didn't see you or that you were riding recklessly.
As that goes, it should be obvious to anyone that if cyclists are required to register, be licensed and pay taxes, that it's unlikely to be immediately followed by the right to stop and roll through intersections that are empty. The more responsible you can be as a cyclist, the less likely it is to be regulated to the point of being worthless in an urban context.
Apologies to all those for whom most of this is obvious.
