While rumble strips are only a minor irritant for me, the series of stop bumps before some rural intersections drive me nuts. They extend across the entire lane so that you are usually unable to avoid them. Don't see why they can't end a foot or so shorter to allow cyclist a path to avoid them on the shoulder side.

They can help warn you that a car has drifted too far right. I've had several instances where I heard the sound of tires on the rumbles behind me. I ride with a mirror so I don't have to depend on just my hearing, but that will scare the ---- out of you.

integrated within the painted line is most logical as it'll enable two vehicle alert warnings before going off in perma dream land of doom.

the county put rumble strips in on a lot of rural highways and the local bike advocacy group got them to re-pave on the shoulders that had substandard shoulders, which they define as 4' wide. I was impressed. OTOH, I wish they had thought about it in the first place. One of the big downsides of rumble strips in the center of the road is that people are afraid to take their giant 4wd off-road vehicles across a few small bumps, so they pass too closely.

I met the Penn State professor that helped PennDOT evaluate rumble strips. His test involved riding a mountain bike down the rumble strip designs. So that's why they are so rough. He's an idiot in person too.
