Well, yes, stopping at a T intersection just for the sake of stopping does feel silly as it does with a four way stop were you can clearly see that no one is coming. I think the informed choice is made at each specific occurrence and each person's comfort level and focus while riding is different. I like to err on the conservative side because in a quick instant like that I know that I am capable of choosing the wrong course of action, like forgetting to consider that a pedestrian might enter the equation. It only takes someone being at the wrong place at the wrong time to cause an accident.

But I have done the same thing as you on occasion and run that red light.
