Yes, if possible I pull over to let them pass.
As a counter I am encountering a lot of people driving well under the speed limit at the moment, e.g. showing 26/7 on my speedo in a 30, 40 in a 60, 50 on a motorway with no significant traffic, etc.
That might have something to do with the fuel price.
But frankly i'm amazed how much traffic is on the roads these days even with an astronomical fuel price. Seems to suggest that people aren't too bothered about the cost.
