ok, these aren't the most attractive things, but are quite subtle in looks

anyone got these? i regularly like to have my window open, be it in warm, wet, cold weather, but wind noise is loud at motorway speed, when it's wet the rain drops in etc. hence the thought

 

I know this is not helpful but I have to ask: Why on earth do you drive windows open on motorways? I'm guessing wind deflectors do little at those speeds.
