I have never ridden two abreast except once on a very empty country road for a few miles. As a motorist it annoys me when cyclists do this so I don't. Why? There's just no need. Be polite and give everyone some space.

As for running the red light, I only do it if I can't get the light to trigger AND I stop and make sure it's very clear to go (not a regular event). My regular route also has a couple lights where it's a three road intersection with no road on the right. Occasionally I will only slow way down but not stop since there's not traffic to my right and I have a wide shoulder.

I prefer to be that cyclist who follows the traffic signals so as not to contribute to the bad name a few bad apples give us. Even if there are no oncoming vehicles, we are responsible to ride like we are one. Just my .02......
