Cyclists are often opposed to rumble strips because of the hazard they pose. I once nearly killed myself when I drifted left to avoid trash in the shoulder and into the nearly invisible rumble strips alongside US Highway 66 near Lyons, Colorado. The Amish in Michigan don't like them because rumble strips are positioned perfectly for the left buggy wheel, resulting in a very unpleasant ride.
