Abby, well done about the distinction between perception of safety and actual safety. I would expand this to say that bicyclists need to know about the hazards that are likely to cause problems — road defects, turning cars, car doors opening — rather than the ones that “everyone knows” are a problem (just being in traffic because the big bad cars will mow you down). There is much wisdom in what you write. I have a few amplifications to suggest, following your numbering:
1. Just stay a door’s width away from parked cars (except maybe when there is only one or two on the block and you can see they are empty). Dooring is the most common city car-bike collision.
2. Do not pass the stopped cars at all if there is a chance they could turn right (this relates to your #3 and #5). Besides pedestrians crossing, there is also the possibility that a car from the other direction could be turning left across the stopped traffic, into your path.
5. There is also the option of waiting behind — especially behind a truck or bus, since large vehicles making turns are the most common source of urban bicyclist fatalities.
6. Making this type of left turn may force you to wait twice for a green light at the same intersection, and also may put you in the path of cars seeking to turn right on red. Once you have mastered looking behind (your point #4), merging to the center of the road well before making a left turn is not difficult on a single-lane road (especially if there is a left-only lane), and only a bit more of a challenge on a road with two lanes in each direction. The earlier you start to prepare your move the easier it is. The two-stage left turn you describe is always a backup option if traffic is very heavy.
7. It’s important to understand that signaling shows your intention, but does not give you the right of way. Therefore if you are signaling because you want to get in someone’s way (to prepare a turn, avoid stopped traffic, etc.) you need to be looking back while signaling. After you are in good position to make a turn, then you can just stick out your arm without looking behind to make it clear what you intend to do at the intersection.
8. I’ve heard “bike like you’re invisible” repeated many times, but it is really not the right message. What we bicyclists need to do is to make sure that we are visible. That means lights at night (your #10), and don’t ride in a way that puts you in places where drivers are not looking for traffic: stay off the sidewalk (riding on the sidewalk makes you very vulnerable at intersections and driveways, plus invites collisions with pedestrians and street furniture), ride in the direction of traffic (on the right half of the road on a two-way street, and in the legal direction on a one-way street), and don’t pass on the right (already covered).
