route on it (so you can suppose you're actually in there). Or rely on 
external, real-time sources of information.

Usually, until somebody builds a 5-kilometer-long reversible motorway 
tunnel...

Yes, I realize this is quite rare, but there are also separated high-occupancy 
lanes that work the same way.

Not really... I should find the time to make a proposal for the tag.
