I have recently removed the roofrails of my car, because they never get used and increase drag. However, on new wagons/estates I'm am noticing a trend.
All of these new cars have roofrails which are closed on the sides.
2014 Ford Mondeo Wagon
2014 Honda Civic Tourer
2014 Peugeot 308 SW
Is this a styling thing of the past, because most people want roofrails on a wagon, or are they actually channeling air across the roof to the rear spoiler in a better way?
