From what I've read about it, you still have to follow all posted speed limits and stop lights and other signs because those are laws without contradiction. It's simply a flaw in the way that the laws were written that leaves certain things to be interpreted in a different way.
It's similar to open carry laws. You could walk into Wal Mart with a shotgun slung over your shoulder. As long as you aren't threatening anyone and it is unloaded it is perfectly legal. Will people be scared and call the police? Yes. Will you get arrested? It's possible. Did you actually do anything against the law? No.
