You're completely off base here. I'd say I do this 10-15 times a day. So ~100 times a week, and there is never an issue. I am infrequently the first car to do it. I put it in quotes because it is a very common practice in SF. You would have to wait through every light twice to get anywhere in the Mission if you didn't do this. It's mostly single lane with no turn light. I noted that it was odd because I very rarely have problems doing this.
