I get a lot of advice of claiming your lane, and that is your right (probably), but you can be dead right. I have been rear-ended three times in my lane in a car in the city at speeds that would have flat killed me on a bike.
You have distracted drivers and on top of that are not tuned into a bicycles. I will take my chances riding on the right unless there is physically not enough room for a bike and vehicle. I have been bumped into the ditch, but I walked away. I will ride the sidewalk if it is legal. Number one, I will pick routes with a bike lane even if it is twice as far. Number two, routes that have room.
If that picture is to scale there is room to get around so I would hug right.
I also ride a cyclocross with big touring tires so I can hug a curb or ride off the pavement if dirt rather than a curb. I race CX and can hug and jump a curb and ride dirt.
I get there are statistics of taking your lane versus the number of accidents, but my take is the reality of getting killed. In taking your lane the problem is if they are not paying attention; then you have taken away their out. Someone on the cell phone in the left lane jumps over; boom, they have no room, but to run you over. To the right, if they are hugging right and don't see you until the last second, they just have to jockey a couple of feet.
Light up - a flashing light is your best defense in my mind.
Right hand turn coming up is the most dangerous situation (even if you have a bike lane).
Rush hour is the absolute worse as you not only have more cars, but you have people on autopilot.
To the right you will have more debris and broken glass.
On my commute there is a 12-block section where I have no option but to claim my lane, and it is flat scary. Cannot ride the sidewalk in a business district in my town. There have been like six instances of car changed lanes and flat had to lock up the brakes to not hit me. If I ride the car pool lane they get mad. If I ride the non-carpool they tell me to get in the car pool. I have even had buses tail me and honk the horn. Talked to the bike police, and they told me I have a right to any lane.
In a city with a bike culture like Seattle you can typically claim your lane and will be respected. That culture is not shared by all cities. Road rage is reality and a bike is going to lose. If they honk don't flip 'em off - wave, pull over, and let them pass - my exception is if there is a red light ahead. If you are first at red light and there are only a few cars behind you then pull over and let them by. You may have a right to the lane, but you just don't have mass to defend it. My favorite is follow a bus or large truck - they don't accelerate fast and with drafting I can typically hold traffic speed. The downside is bus stops, but I use that as a rest. A lot of buses and trucks don't like you in their blind spot, but I still do it. At stop, pull out in their mirror so they know you are there. If they are turning right or left then pull back so they can see you in their left mirror.
I accept the downvotes. But I have commuted to downtown in one of the biggest cities in US for over 10 years with no major injury, but with a number of close calls. I feel like some of the close calls would have been splat if I had taken the lane.
