Its a facto, but I think people also do think it makes more a difference than it does.
One thing I have noticed from using satnav is that even with a mostly motorway journey the difference between driving fast and driving at a more leisurely pace is never more than a minute or two per hour compared to the predicted time.
I knew it from seeing how often I later caught up with someone driving very aggressively, but quantifying it made me realise just how consistent the small difference is.
