The rumble strip isn't there to keep them from hitting cyclists riding on the gravel shoulder. It is to warn a driver that they are about to drop from the pavement at speed and possibly lose control. A buzz to the wise is sufficient. But if they choose not to heed the warning that's on them. Odds are they won't hit anything more important than a rattlesnake even if they roll over completely.
