But as soon as someone comes up with an effective way to implement, say goodbye to rust forever.

Yeah I know the devices you're talking about. They're rediculously expensive and really don't work that well, because as you said, they can't cover the entire car. However, sacrificial anodes do the exact same thing, but at a small fraction of the cost, and so would be far more cost effective to implement in more areas.
