I'll grant you that in the situation you described it was justified to run the light (of course you're making a split second decision and hoping not to t-bone that child in the car seat). That is a one in ten thousand circumstance. No system is perfect.
There was no approaching cross traffic; all lanes had cars waiting at the light. Given that I would have almost a two-second head start on any cross-traffic motorist, and that I was flooring the accellerator, the risk of anyone actually managing to get in my path was pretty slim.
Besides, there would have been more danger to cross-traffic motorists if I'd waited at the line for an extra second or so before I got pushed.
