Talking about "this exit" only makes sense to me when you are near an exit. If you're well in between exits, then I would think there is no "this exit". There's only the previous exit and the next one. I think it's normal for car navigation systems to say "take the next exit", when you're not there yet. Applying the same logic to weekdays, if today is Wednesday, then next Friday is the one in two days. And one would never say "this Friday" since it can be called "today".
