Our road has enough places to pass so I might get a couple which I kind of like as a buffer. Last year going down with my planter I did pull over to get out of the way of a big Deere with a big planter.If you get a line of cars behind you you can always find a place to pull over and let them pass.
Best was a bicycle when I was on the WD one day. He passed me on the down hills and I passed him on the uphills. back and forth 3 times.
