I wish I had replied to this back in 2013 so @Whereisthebus could be yelling at me from out of nowhere too....
As i tell those that I have hand in helping learn to drive: Do not let someone else control your driving. Whether in your car or outside influence, you have to be in control of your own vehicle. Don't let someone else influence when you feel comfortable to move.
This is also why we start out on side streets and empty parking lots- so the comfort levels of just being behind the wheel can grow without traffic pressure.
Right on red? If legal and you are comfortable doing it- go for it. If not, stay put.
