I don't run red lights, or blow through stop signs.
I will make a left turn from the left lanes, as that is fitting, proper and legal ( where I am, anyway ).
Otherwise, I keep to the right and make sure I am predictable, and try to be courteous to all.
It is still dangerous.
I agree completely that a cyclist should obey the rules of the road. It annoys me when they don't, as a cyclist, as car drivers seem to take a "all cyclists misbehave, so I can run them over" attitude. But that is all window dressing. Riding a bike in traffic is dangerous because automobile operators, in general, don't look, don't see, and don't understand ( excluding a few that do, and a few that seem actively malicious*. ) I would expect you would know that from riding a motorcycle, I have noticed that cars seem to act the same there.
* I am alive today thanks to ( short list, there are others A, 2 metal posts I could ride between, but the car trying to run me down could not, and B, a curb that I hopped up that the car chasing me was not willing to try to get up ).
Note, just ridding my bike where I was allowed to.
