For me, confusion in top-down navigation happens either because there's no bitmapped imagery being displayed, forcing me to guess where the turn is by mentally wrapping vague 2D geometry over the scene viewed through my windshield, or because the trace isn't drawn precisely enough over the imagery that is available.

I don't see much added value with this particular nausea-inducing approach. It falls into the category of "You should've thought less about whether you could and more about whether you should."
